The Copper Fouling Lie ~ Don't Fall for It!
HTML-код
- Опубликовано: 19 мар 2023
- Purveyors of copper removing solvents have created a major industry on the demonstrably false premise that you must faithfully remove copper from your barrel to maintain accuracy and prevent the buildup of excess pressures. Don't let them profit at the expense of your rifle barrel!

In an age when common sense is uncommon, it's nice to gather wisdom from a wise man who gained wisdom through experience and time. You're a national treasure!
If the guy told you to put a pin needle into your pee hole, would you do it?
Of the firearms guys that I watch with any frequency, not all of them are trying to sell me something. But you’re the only one who actively tries to help me keep the money in my bank account. Much appreciated.
When I started precision rifle shooting I always cleaned the barrels with a copper solvent after 50 rounds. Next time on the range it took me about 8-12 fouling shots just to get the point of impact back where it was before and to get back proper precision. After a while it dawned me how dumb and also expensive that practice was and never removed the copper from barrels since, and after many hundred rounds through my .308 and .300 they still hold 0.5 to 0.75 MOA consistently.
That was exactly our experience. It creates cold clean bore syndrome.
@@GunBlue490 should I fire copper jacketed ammo for my .22LR rifles? I think I only have used lead bullets on some of them eg Aguila super but I have some cci minimags...
I think I've answered my own question 😅
@Bear Gillium the copper on 22 lr projectiles is more a copper wash or coating that is far softer than a jacketed centerfire round so it shouldn't do anything much to the bore.
If anything its cleaner than using straight up lead projectiles.
What cleaning solvents do you use?
@@GunBlue490 so you acknowledge it exists, but you choose not to address it because it’s not absolutely necessary?
My first rifle was a 1917 Enfield. For the first 30yrs all it ever fired was military ammo. My Dad taught me to clean it with boiling water and when clean run a couple of patches with 3in1 oil through it. Did the same for the next 28yrs using mostly non corrosive ammo. After 58yrs and thousands of rounds it still shoots the same. Its the most accurate rifle I've ever owned and just cleaned with hot water.
I love 3in1 oil. That stuff is a hidden gem amongst all the razzle dazzle gimmicky clever advertisement oils
Good tips thx
Surprised your dad, who you claim used it for 58 years, did not tell you the reason why he put boiling water through it after shooting what you claim is "military ammo."
@Dan-di9jd
Where did he state his dad used the rifle for 58 years?
For a 1917 Enfield to only fire military ammo for the first 30 years of its life is to be expected. They were retained by the military until after WWII.
@Dan-di9jd your comprehension is peerless.
Thank you for covering this, makes good sense to me. As always, another informative and thought provoking video, much appreciated.
Turning 74 this month, and I'm still trying to graduate from my "dumb and stupid" phase when it comes to all things ballistic... More good stuff from one who knows.
I often think back to the time i spent working with my dad. He allways had a better way of doing something that was not only easier but cheaper too. You remind me of him and i love to listen and learn from your life lessons you share with us, God Bless and say high to Bengie.
Thank you for this information. I always suspected as much. I also enjoyed your video some time ago on the spring fatigue lie. Everyone should watch that video and save money on springs.
I was under the impression that once the copper deposits stabilize, accuracy increases.
I'm far from an expert, but I appreciate the logic. I'm also too lazy to remove the copper fowling and all my firearms shoot just fine. Another great video from the man!
*Fouling
First off thank you for your service. my dad who passed away a few months ago was in the 1st and the ninth air cavalry at about the same time as you. As a mechanic I will tell you that most crankshaft bearings are a copper alloy. I have spent way to much time trying to get the patches to not look yellow then gave up. Now i will just leave it be. I'm glad that I found your you tube channel . i've learned so much. thank you.
Thank you once again for your honesty and expertise! You are a dying breed for sure and we appreciate and love you! From N.C.
I enjoy these "sit down" videos.. I too am a mineral oil convert, thanks to you ! Its amazing how clean a gun gets with a paint brush, a slop of mineral oil and an air compressor, in less than 5 minutes !!!!
Regarding your story about the shooter who was swabbing his bore with a caustic substance every few rounds, one of my customers in New Hampshire reported a very similar experience in the 1980s. I had sold him a match grade AR15 which was supposed to print half MOA groups. Within a couple of weeks he returned it to me claiming he could not longer keep his shots on paper. I shipped the rifle back to the manufacturer for inspection. I later received a call from the owner of the company who informed me all the rifling was gone. Further inquiry with the customer revealed his practice was to stroke the bore at least five times after every single shot with a stainless steel brush and a strong solvent he had acquired from Canada. He had effectively lapped his 416 stainless steel, broach cut barrel until there was no discernible rifling left. The manufacturer charitably agreed to replace the barrel on the condition he cease this insane practice and stop using this particular solvent. People have asked me in disbelief if I knew what the solvent was made from. I think it contained ammonia, but aside from this, I don't know because the customer never told me.
I'd lean more to his brushing the heck out of the bore with a SS brush, rather than the solvent. But I wouldn't be brushing every shot, either. Did the buyer say WHY he was doing that ?? Personally, I just watch for cra* in the rifling grooves b4 I 'scrub' a barrel.
@@fasteddie1360 He believed the least amount of debris adversely affected accuracy. Apparently he was wrong.
@@fasteddie1360
The brush has to be softer. A friend of mine gave out a rifle in afghanistan and the same day it came back clean as can be but with most of the rifling gone. Others worked out...that one was going all around the base to look for 'better' ways to clean the barrel and got his hands on an oversized hardened brush from some helicopter maintenance crew.
Oh yeah….blame Canada!
Maybe he mis-understood "which bore" to stroke with that SS brush -OOOWWW ! Gotta watch where you apply that thing.
I remember an older video you made about whether there was a need to clean cases before reloading. Well I'll thank you here and now for all the time I've saved reloading since watching that video years ago!
I never bought into the Copper Fouling mantra either. I agree with your thoughts on copper filling in the striations in a barrel. It makes perfect sense. Thank you for sharing your knowledge so freely. I truly appreciate it. Hope you and your family and Benny are well. God Bless and keep you.
So glad you spoke about this, I have been fighting this fight for years of filling pot holes and leave it alone. I have an old 700 BDL in .270 and they built this one right. From day one it was a clover leaf at 100, and it got better over time. Longest shot on that rifle 445 paces across a prairie slightly uphill nice buck antelope and his does surrounded him so I only had the cervical spine shot he was facing me. Still in my safe and it will never leave! Maybe someday speak to leading and carbon build up? Great conversation thank you sir.
Thank you for this video! I’ve heard of some shooters talk about cleaning out copper, but I’m with you it’s actually a good thing for copper to season a new barrel. I work on getting carbon out, I never worry about a copper cleaning.
Great info, thanks. I have copper solvent and have been afraid to use it. You have confirmed my suspicions about using it.
Amen! Thanks again for your wisdom, knowledge and steady guidance.
Thank you for not being afraid to speak the truth. I see so many videos where firearm enthusiasts speak wrongly on copper fouling . Many a barrel has been ruined by using the wrong cleaners and cleaning products by those who are obsessed with cleaning every bit of copper fouling from their firearms .
I met a shooter who said it took him 8 hours to properly clean his Colt Competition H Bar . He described in length his cleaning ritual. The one thing I'm sure of he was working on destroying a good rifles accuracy and barrel .
I appreciate sharing your wisdom on this... God bless you and yours
Thanks Blue! Your knowledge and wisdom is invaluable.
My father told me this at the age of 9, he’s was a bowl maker machinist great video.
what a man, father and machinist by the age of nine, hats off.
Since I have been following your instructions on youtube, I only use odorless paint thinner to clean my firearms with excellent results! I do not even want to think about the money I spent using the marketed solvents, CPL`s, blah, blah, blah. I was a cash cow to those companies for years. Sir, you definitely know what you are talking about! Thanks, and God bless you!
Wise words from a wise man. I have also learned this the hard way over time. If something is strong enough to turn patches blue and strip copper out of your barrel, it will eventually do the same to hard chrome lining.
Thank you. I've often wondered about the wisdom of and need to remove any copper from my barrels.
Thank you for sharing your faith, your firearm knowledge, your construction know how and your culinary skills. Sir you are" smarter than the average bear" by far. God bless you and your family.
He's a gun smith. You do understand that barrel makers tend to tell their customers not to clean their barrels? And gun smiths would tell their customers not to do anything with their firearms. Want to know why? It's so you can continue to buy from them as you wear your stuff out. Like anything out there, taking care of your equipment is going to go a long ways. If you clean your firearms with approved chemicals and methods, then you're going to have a firearm that's going to last for generations.
@@Dan-di9jd Which barrel maker tells their customers not to clean their barrels? Examples please.
I can't tell you how much I appreciate your input. You've made me a better marksman, hunter and generally better educated sportsman over the past few years. Thank you sir.
So glad to see this one, thank you !
My concern was not "build up" , but that the softer copper would cause some possible drag effecting MOA , although I was aware of the "filling the inclusions" concept.
Makes complete sense. Thank you for your sage advice.
Always a pleasure watching your videos 👍 thank you for sharing the knowledge
Your drywall screw analogy was perfect. That’s exactly what I thought
excellent video sir! after cleaning the barrel of my Garand and the patches came out clean. I figured since it's over 70 years old, I would use a copper remover two get out any crud that may have built up. with one pass, the patch came out blacker than black. I don't know where that stuff found the powder residue, but at least I know it got a good cleaning. Will I ever use it again, nope. I know that from now on standard cleanings will keep it in tiptop shape. Thanks for the video!
Yet another aspect of gun maintenance I need to re-think🤔I've noticed after brushing the bore on my Mini-14,it will shoot off to the right until I've fired a half dozen or so fouling shots.For now on,patches only for the bore,chamber brush only for the chamber. Sir, your extensive gun and shooting knowledge and experience is much respected and appreciated. Thanks again👍
With age comes wisdom listen up thank you for your Channel I don't have nearly as much time under my belt as you do in my early sixties former Army infantry served in the early 80s appreciate you peace out from the West Coast dump truck driver be safe be well
In rifle bore cleaning ( for the Lazy shooters) there is videos that claim copper fouling or carbon fouling is not a problem . Copper fouling will build up if not removed . How much and how soon depends on the quality of the bore , but regardless , it will build up if not removed . Either fouling will affect accuracy at some point.
My experience has told me the same thing. Copper fouling will definitely build up! Along with Carbon fouling! When accuracy is affected, the stubborn process of clearing it out and seeing accuracy regained will make you a believer! This is one of those videos you speak of...... Experience has taught us otherwise!
This is great.👍 We consumers are constantly told that any copper wash in the barrel needs to be removed with Brand -- copper solvent. Thanks for this video.
Great information. I appreciate your vast knowledge.
I'm telling you, an American treasure.
I’m from this camp too…just about to go the way of the dodo but you’ve just reassured me I’ve been doin right
Thank you for sharing your views & opinions as well as your in dept kniwledge.
I just subscribed. This is the 3rd video of yours that I've watched and I have learned something new each time. I appreciate your experience, knowledge and willingness to teach and share. Keep up the good work!
Sir I agree, in the 1990's I scowered my barrel to rid copper to only find accurcy to deminish utill it was reastablished !
I have never cleaned copper fouling out of my barrels, and my main hunting rifle in 338 win mag shoots sub 3/4 moa all day so long as a person can handle the recoil.
My vintage Brite-Bore cleaning kits that I got from an uncle didn't have anything in them about removing copper, and neither does my Hoppe's cleaning kit. So I didn't know it was a "problem" until a few years ago when I was hearing about it through marketing. Instead of jumping in feet first for the "latest and greatest" in gun cleaning I just followed what my vintage kits recommended as I never had a problem with my firearms, and I figured that they knew a thing or two about cleaning guns back in the day. In my mind if copper fouling was an issue they would have discovered it by then.
Thank you for the wisdom. I have always cleaned the barrels of my rifles because that's how I was taught, until I started hanging around real gun guys and they informed me that I was doing it wrong. Now I use a polymer brush every now and then to get the carbon out but that's it, and I use hoppes #9 to clean the action, bolt and levers.
Thanks for sharing you experience… I totally agree with this.
Blink twice if you are referring to Sweet's 7.62 Solvent, a highly corrosive copper solvent. In fairness, the directions on the bottle warn not to let it remain in the bore or other metal surfaces longer than 15 minutes. I used it about two times and was scared off, but the .30 caliber ammo can that I stored all my bore cleaning solvents, especially Sweet's, reeked of ammonia and literally peeled the paint off the interior of the A-box, I discarded the bottle soon after. When the U.S Military's ammo was corrosive, it was thought that metallic fouling would cover areas of the bore which contained corrosive salts deposited from previous rounds and that it was imperative to remove the metal (copper or Antimony) fouling with a solution of Sal Soda which was mixed under the watchful eye of the Drill Instructor, then with all fouling removed, hot water would be swabbed through the bore to wash away the corrosive salts (info taken from 'Manual For Non-commissioned Officers And Privates OF Infantry Of The Army Of The United States 1917_ Revised To June 4, 1918'.
I was hoping it was not 'Shooter's Choice' solvent. I used that for a couple of years. Did not seem to hurt my barrels though. I went back to Hoppe's though, and will never change again.
@@nathanlambshead4778 amen. i've never had anything work better than Hoppe's for my needs. (pistol, HP / Service Rifle XTC). If I shoot three matches in a row and the Hoppe's isn't working fast enough, a patch or two of JB does the trick because it's exactly what it says... abrasive paste to bust out the carbon. When the patch runs through smooth then I hit it again with a pass or two of Hoppe's and she's slick as a whistle.
@@nathanlambshead4778 all the good solvents contain some degree of ammonia. Yes, so does Hoppes. Ammonia does not hurt the barrel just by normal basic usage
@@John_Redcorn_ true but Hoppes also obtains rust preventative as well. Plus it just smells great.
Funny thing is what got the corrosive salts out was the water, not the solvents.
Always a teacher. Wonderful lessons. Please keep educating the community.
I appreciate your videos. I too have always believed in how you clean your gun barrels. Thank you for sharing this video.
Great topic. The other ones are bronze bore brushes and barrel break in processes. We've created a pile of landmines for the average person.
I didn't start shooting until the mid '80's. One guy at work had spent 20 years in the military. He told me that far more rifle barrels had been ruined with a cleaning rod than had ever been shot out. One or two wet patches with good old Hoppe's No. 9, then a few clean patches always being careful of the muzzle crown was what he suggested. A trace of gun oil if the rifle was going to be put away for a while, like over the winter, nothing more. I've never had a problem with one of my rifle barrels.
He's probably right about too much cleaning but the military has a habit of wanting those weapons spotless before they would be allowed to be returned to the arms rooms.
I have a few ar's that I have never cleaned the barrels. One has over 5g rounds. I wipe the bcg down with a dry rag and re-lube it that's it....still shoots good
@@gmac8852 not to mention troops would use brake cleaner & other harsh solutions to quickly get carbon out to pass inspection... doing that after in many cases only shooting 40 rounds...
@@JJ_SDWR Yeah I was using all kinds of stuff including homemade picks and scrapers .
I have NEVER seen a barrel worn out by a cleaning rod in my 54 years, that is another bull shit people buy into!!
At 10:00 that's a good point you make. Copper is incredibly resistive to the elements so anything that can break it down has to be extremely caustic/corrosive. Copper is what they used to plate the bottom of warships in the 19th century. Galvanic corrosion is the only thing I worry about with copper in the bore and it would quickly corrode the iron fasteners used to attach the copper plating to warships, but only because salt water makes such an excellent electrolyte. How great of an electrolyte the air is depends heavily on your climate/humidity/temperature/sea spray etc, but can also be prevented by using a light coating of oil to seal the copper and iron from the air, ie regular maintenance.
Oil in a barrel? If excess copper gets blown out with each shot, why wouldn’t a hydrocarbon compound?
Caustic doesn’t mean corrosive. It means, highly alkaline on the pH scale. Which in the case of steels is actually the opposite of corrosive. Just because a solvent reacts with copper does not mean it reacts with steel in the same way. In the case of copper removal solvents, the active ingredient is almost always ammonia. Steel is highly resistant to ammonia but copper is highly reactive with ammonia. Just trying to get the right info out there because this stuff is not common knowledge.
Great video. Thank you for passing on great information.
Great video. My two favorite shooting resources agree on this.
Once again Sir thank you for addressing the copper controversy with factual information in a clear,concise and logical presentation.I’ve watched several of your previous presentations on gun cleaning and I only use mineral spirits(Hoppe’s #9 love the smell) and mineral oil.I’ve watched several other videos where they go into great detail on removing copper with their copper removing product.Something in the back of my mind told me to take their info with a grain of salt and now I know it was because “if GunBlue490 doesn’t recommend it forget it”look forward to your next information session.Brian Levin BC Canada
Do you use Hope’s #9 to clean your barrel with the one that says solvent or without?
Thank you gunblue from your experience in this confusing topic. I used to clean my barrels with copper foul cleaner but not anymore. Luckily I haven’t had any issues with those barrels, seems to be working fine now since I’ve been using your cleaning methods with simple cleaners. I recently purchased a savage axis II precision 6.5 creedmoor. Shot a box of ammo first before I cleaned the barrel with a copper bristle brush with standard solvent and oil. I smoothed out the barrel with the brush back and forth around 10 times or so until the barrel felt smooth with the brush just like smoothing out a brand new wall getting rid of the access putty. I went out to the range to check for accuracy improvement and man does that savage shoot! It’s a tack driver. I guess I’ll get rid of my copper foul cleaner, don’t think I’ll ever use it again. I love your videos gunblue!!
Good advise..I never believed in barrel break in theory either!
Thanks for this info. I had come to a similar conclusion just from personal experience. I'll continue on just cleaning up with a boresnake and some Ballistol or synthetic CLP. Cheers.
Finally, the excuse I've been looking for! I'm not neglecting my rifles, I'm curating copper!
Copper is one of the main ingredients in high performance alloys of bearing bronze that practically slip off unlike metals🤯
Seems like “copper fouling” is another attempt to market more products to government agencies and the average consumer 🤷🏻♂️
Spot on.
@@GunBlue490 I have always just used hoppes number nine for everything swab the barrel then a bronze/ brass brush wipe dry oil and wipe out. But I do need to find something that works good for leading in my revolvers from shooting a lot of cast bullets
@@JamesBond-so1of Why? Lead is even softer than copper and by this logic should only continue to make your firearms more accurate.
@@JamesBond-so1of Well Mr. Bond or should I call you 007? Years ago I was a Brinks Canada instructor and it was all S&W revolvers in 38 Spl. We normally bought jacketed ammo but there was one time the only 38 Spl we could find was Federal American Eagle 158 grain Lead Round Nose. Thankfully it was a week at an outdoor range. Over that week there were thousands of rounds fired and at the end of every day the revolvers cleaned.
M-PRO-7 in the big spray bottles was what we were supplied for cleaning. I’ve watched as both blued and stainless barrels would get strings of soft lead exactly the same size as the barrel grooves pushed out after those barrels were sprayed and mopped and let soak for a while as the trainees cleaned the exteriors. Then using plain old bronze bore brushes some of the barrels released these lead strips upto .75”.
Never witnessed it before or since and I was loading my own lead semi-wad cutter rounds on a Lee Pro-1000 and firing them out of S&W Mod. 19.
@@timothyrepp4259 lead is too soft, it galls and leaves lead in the rifling not just the machining marks.
I thought it interesting, I purchased a "custom" rifle from Montana Rifle Co (since out of business - what does that tell you ?) and it came with a sheet that called for thirty shots with jacketed bullets, in groups of ten and cleaning. And I was scratching my head, and has been bugging me all these years. So glad to hear this - better late than never.
My gunsmith tells me the same thing this video did. He has all kinds of trophies, said all he ever used Hoppes 9 original.
They dont usually call for copper solvent though just regular cleaning.
Did they suggest using a copper solvent? Breaking-in a barrel is a totally different topic than whether or not to clean out copper fouling. And it's another controversial topic, haha.
I like this old timer, full of knowledge, and experience
Thank you. What you said makes sense. Best wishes from New Zealand.
You may be right about most barrels but not all. My 17hmr will copper foul after about 100 rounds. Accuracy goes out the window. Once it's fully cleaned it goes back to sub moa. I have owned it since it hit the market. When the barrel was new it would only go about 20 rounds. So at least in 1 case copper fouling is a thing.
interesting video. I was a law enforcement sniper/observer for numerous years. The group I shot with monthly would always harp about keeping their barrel clean and copper cleaning their guns frequently. (and go nuts on me when my cleaning kit consisted of a bottle of solvent and a boresnake) I had an older Remington 700p that I shot until the barrel started to finally give out (in excess of 5,000 rounds) and start to open up. We would have our guns barrels scoped once a year to check for wear, erosion and firecracking. I would always clean with Boretech copper cleaner prior to this inspection but that was the only time. It was a pretty mild copper cleaner and you would have to use their aluminum shaft/nylon bristles in order to prevent false positive patches from being pulled out when cleaning. Other than that, my philosophy was that I equated the copper to asphalt filling in the potholes in the road and making it smoother. I thought it was funny you equate it to spackling sheetrock. Same thing. My cleaning regimen (good, bad or indifferent) was usually only pulling a boresnake through 2-3 times tops after running a patch down the barrel with solvent. That was pretty much it. The rifle would always shoot 3/4" consistently which was about all I needed. Whenever I did the "deep cleaning" of removing all the copper, the groups would open up substantially and shift, until I had 5-10 rounds down the barrel. I definitely think you're on to something!
People get fleeced by anything these days because marketing can be very convincing. Just like the news -but I digress. It's great to have people like you to keep us grounded and call out the B.S. that gets circulated.
Thank you for your words of wisdom.
I have become exhausted by having arguments in comments sections over this. I officially no longer care to try to save the RUclips shooting community from themselves. I tell people I curate copper during barrel break-in to improve accuracy, and I get no end of push-back from about two generations of self-proclaimed-know-it-alls. I'm over it, lol.
What does that mean to "curate copper"? Never heard that term before?
@@jeffdonofri8027 Deliberately allow it to build up and collect in parts of the barrel that are otherwise imperfections in the cutting of the lands and grooves of the rifling, and purposely leave it there.
@@jeffdonofri8027 Like: what do you do when you curate a collection of anything. Some things you save, some things you don't. In this instance I'm removing lead and carbon fouling, and retaining copper. It isn't like I read it somewhere, I just used the words curate and copper together because, well, it is a short way of describing it. So much for that plan though...
Is blue on the cleaning patch a bad thing? Remove carbon only?
@@davidpaulk5658 blue or greenish is the copper coming out
My first fine rifle was a .243 with a very accurate Shilen heavy-varminting barrel. I shot hundreds of rounds through it, just cleaning powder fouling out of it periodically with Hoppes #9. Eventually it started blowing burned powder around the bolt into my face. When I took it to the gunsmith, he chewed me out over the copper fouling, saying he had to soak the barrel in copper solvent overnight to remove the fouling, because it had built up so much. He told me never to let my rifles go like that again. He'd been in the business decades. He would know. The next time I shot the rifle, it was fine again.
Tony Boyer, the most successful benchrest shooter in history, recommends (Chapter 17 "Cleaning the Barrel" of his Book of Rifle Accuracy) cleaning the bore of a benchrest rifle every 20-40 rounds. He mentions the use of Sweets and Montana Extreme solvents, which are designed for copper fouling. He starts that chapter out by asserting that copper as well as carbon builds up in the barrel as you shoot.
A factory rifle may have a barrel with a significantly larger diameter than a high-quality barrel like a Shilen, Krieger, or Lilja, so it may take hundreds of rounds of copper fouling before pressure increases would become a safety issue. My barrels are all of benchrest quality. I'll continue to follow the advice of the smiths who build my rifles, and of Tony Boyer. Once you've had burning powder blow back into your face, you take a dimmer view of the idea that copper fouling doesn't build up and require periodic cleaning.
I agree. There's definitely copper in the bore, and a simple patch with an ammonia based cleaner will prove that. A bore scope will also show this. I've purchased rifles (for a song) from guys that told me the barrel was "shot out", and on every one of them, a good cleaning was all that was needed to bring them back. And yes, copper was part of the issue.
Great info. The commercial industry sells us a lot of things that we dont need. It does what they say, but we dont need it.
This is the first time I've stopped to listen to an entire video in a long time. I liked the information a lot - thanks for the info. I was feeling like I was slacking on my care because I don't do much but use CLP and have for about the last 5 years.
I've shot thousands and thousands of rounds through all sorts of weapons during my years in the Army. This is spot on. I never once noticed any copper fouling in my barrel after a quick boresnake run through. If running boxes and boxes of 7.62 through a 240 machine gun at 640 rounds per minute won't do it, I don't think anything can. I also agree that the military spec CLP doesn't do much for cleaning besides stink things up. After the range, I always snuck off with my soldiers to the ultrasonic solvent tank when in garrison if I could. That thing works miracles.
If it won't shoot dirty I won't own it
Thanks again for great information. Enjoy your videos.
Thank you for telling the truth. I've been saying this as long as I've been shooting, and I've taken a lot of guff from any number of "experts".
I'm amazed at the amount of things I've learned from watching your videos.
So many things that I thought were fact turn out to be false and at my age it is hard to believe how long these falsehoods were believed and accepted.
Thank you Sir for the simple and easy to understand logic that you present in your talks. I find your videos fascinating and helpful.
I've always used Hoppes #9 but the mineral oil is a new one for me. So sensible.
Transfer that same logical deduction to history, everything the government has done and current affairs and you'll be even more amazed.. tho you might want to tie a rope around your waste before you start down the rabbit holes, they're pretty deep and dark.
I clean with Ballistol never had any type of problem.
I've come to the same conclusion and appreciate your video confirming my belief.
I value you opinion , experience and advise, other you tube gun experts could learn from you. Absolutely luv your 1911 slide drop dry fire video… the best!
one thing i would never put on a gun is that lucus gun oil, or anything made by lucus. Test after test shows that stuff does nothing to stop rust
People that depend on accuracy for a living, the National Match shooters do not clean their barrels. They clean the upper/lower, receivers and the bolt carrier group. The only time they will clean a barrel during a season is when accuracy falls off.
I first was told this information from an old friend of mine. Your 100% correct mine and his experience backs up everything you said.
Thank you for the info. Just threw an almost full bottle in the trash. One less thing to worry about.
I think your correct for most mass produced factory hunting rifle barrels. They're so full of imperfections they need a filler. On a custom rifle cut and lapped barrel I think it's a different story and I would only use nylon brushes with carbon cleaner and patches with mild copper cleaners. I doubt you would find a top 20 competitive bench rest shooter that doesn't remove copper from their barrel and those matches come down to 0.001" or 0.002" between winning and losing.
No, the latest cold hammer forged factory barrels are absolutely not full of imperfections and rival hand lapped barrels made on old fashioned broaches. What you doubt is not a statistic. Please supply factual statistics with competitor's names.
Any serious BenchRest competitor, or LONG RANGE competitor
I've had different experiences with copper fouling in different rifles. I had a Remington 700 in .308 that had an extremely rough barrel that would copper foul excessively. It would take about 5 rounds for the barrel to foul properly to shoot consistent. Then I could shoot about 60 rounds at about 0.7MOA. If I kept shooting, even after removing carbon fouling, the groups would open up to 2 MOA or greater if I kept shooting. Removing the copper fouling would bring it back to a 0.7MOA rifle. I also worked on a 1903A3 that had never had the copper fouling removed. A family member who owned it complained about accuracy. It almost had all the rifling shot out of it and the copper fouling after about 25 rounds would make it a smooth bore. I could actually see keyholes on a 50 yard target. Cleaned the copper fouling out, which took days because of the buildup over the years. It took 2 shots to foul properly and it would hold about 1 MOA for about 20 to 25 shots. After that it needed the copper fouling cleaned out to regain accuracy. I also own a rifle with a Bartlien barrel. That rifle could shoot over 500 rounds and not lose accuracy from copper fouling. I do like the suggestion about not using caustic chemicals to remove copper fouling, if you are going to do so. KG-12 is not caustic. It will not hurt your steel barrel in any way no matter how long you keep it in the barrel. It was designed for the military and large bore rifles. I agree that in general the military isn't worried about copper fouling. That's because they only have a 2-3 MOA requirement. Most of their rifles with ball ammo are not capable of anything better. For the precision shooting I do, I've noticed accuracy degradation from copper fouling in every rifle after a certain point. When you've got a rifle shooting 0.3 MOA and all of a sudden it's shooting 0.7 MOA, that's a problem in my sport. When cleaning the carbon out of the barrel doesn't fix the problem, that leaves only one culprit. Copper!
MY 7X57 Featherweight. If I just run Hoppes 9 through it. Even 50 patches with a plastic jag. they'll all have blue-green color on them. Not the same with my Shaw Barrel on my .25-06. It cleans right up. I broke it in with JBs Bore Paste and Hoppes as recommended by E. ARTHUR Brown Co. where I've bought two barrels. I did NOT do a break in on the 70 Featherweight and it seems to throw out copper with every patch. Only difference besides no "break in" was ones a hammer forged and the two others are Button rifled. My .260 didn't seem to be bothered by EABCOs break in with JB Bore Paste followed with Hoppes #9
A 1903 with no rifling that goes from keyholing to moa accuracy...hmm.
(X) Doubt
@@griftinggamerwell first, I didn't say it had no rifling, I said almost no rifling with the copper fouling buildup. After the copper of 100 years of shooting was removed there was rifling, just quite worn down. This is what sold me on removing copper fouling from my rifles. Years later I proved that copper fouling buildup affects groups at 1000 yards. But the limit is always variable depending on the rifle. I find that quality custom barrels are affected less by copper fouling than factory barrels. However they are all affected in some way. For reference you can look up F-Class John's videos on barrel cleaning and why he removes copper fouling. Or you could look up Eric Cortina and his cleaning routine. These are pros that compete and win constantly. Maybe they're on to something.
Wow! That makes perfect sense! Thanks for the knowledge bomb, Gun Blue!
Old friend you are on the right track l have been shooting for at least 60 years and I have found that is true when I clean my gun I never get good groups until I have shot six times so GOD BLESS YOU AND YOUR FAMILY 👪
I’ve learned a lot about barrel maintenance after having bought a bore scope. I do a lot of accuracy shooting out past 1k yards out to a mile and have found that even after cleaning with hopps and other mild solvents that it doesn’t touch baked in carbon after thousands of rounds. Groves start to fill in, rifling becomes less efficient and bullet stability is lost. It becomes carbon baked on top of copper on top of carbon. I used to be on the don’t clean until accuracy drops but now know that once a barrel has enough crap built up in it that it’s close to impossible to get it out. Everyone that’s into accuracy shooting should own a bore scope.
I'll admit I used to be OCD about removing copper from my barrels after every shooting session, no matter the round count. Now I'm the polar opposite, I only clean it after a ton of rounds have been through it, and I don't try to get all the copper out. I bet the caustic copper remover he mentioned was Sweet's 762. I used to have some of that several years ago but I quit using it because it was just too potent. I think most of the barrel cleaning myths were perpetuated by barrel manufacturers so they could sell more barrels to those who wore theirs out from too aggressive cleaning.
What solvent do you use now?
@@donrowan760 Hoppes #9 for cleaning copper out of the bore.
I switched to boretech and am really liking their products
I use Hoppe's No.9 solvent, I'll run a bore brush through it a couple times, then gun oil with patches till it comes out clean. Like you said, I don't want to remove the smoothness of the bore. Thanks for your videos. 🇺🇸
That's what I do
I love this, I have never ever worried about copper fouling and I manage to shoot a good group from time to time
It’s an interesting theory but I know there are a lot of high level competition shooters that would strongly disagree with you. My problem with your philosophy of never cleaning the copper out is that if you use a bore scope to look down your barrel there are usually specific areas that the copper tends to amass in and it’s far from being uniform throughout the barrel. I would sure think that has to have some impact on the bullet when there is varying depth in the lands from the high and low build ups of the copper. As far as the bronze brush getting destroyed by the copper solvent I don’t doubt it at all but most copper solvents recommend you use a nylon brush anyways. I’m not saying you’re wrong but from my experience and based on the recommendations of world class shooters I will continue to clean the copper out of mine every 100 - 150 rounds or so.
AMEN to your comment . Had a discussion at a club range with a 1,000 yard B.R. shooter , he was in the top 3 world wide . I asked him if he cleaned his bore at matches . He said , every chance he gets . They are allowed fouling shoots before scoring . It's utterly stupid to think that a bore with a build up of cooper is going to shoot as good as one that isn't . Fouling is fouling , regardless of type . The only difference, it's easier to remove copper fouling than
carbon fouling.
I know this isn't directly related to this video, but I would be interested in hearing your thoughts and experiences as they pertain to steel-case and bimetal-jacket ammunition.
The answer is one of simple government economics. Prosperous countries use copper jackets and brass cases. Third world and Communist states use steel cases and jackets because they can't afford what they really want.
I as well went thru the clean all the copper fouling out. Then have to re foul the barrel to get my groups back on target. Duh! Wipe the barrel out to prevent rust and expect the first shot to be same as your last. We get smarter with age. Thanks for confirming what I experienced. God bless.
All I need to say, being a milllright by trade., have machined thousands of my own components. YES! 100% good video.
I recently purchased two new AR barrels from a highly regarded manufacturer. I’d also recently acquired a bore scope. I was disappointed to find my factory new barrels gleaming with copper “fouling” which led me to the mistaken conclusion that I’d been shipped 2 heavily used barrels. I can’t tell you how relieved I feel after watching this video. In retrospect, the coppery grooves in my barrels appeared glassy smooth!
Hmmm.... Your barrels should have been spotless from factory unless they're doing some test firing at the factory.
@@TerminalM193 Never bought a rifle that had a barrel that was not filthy from the factory...not necessarily copper, but just carbon I guess.
@@cbsbass4142 Were they actually filthy though? I've purchased many barrels and uppers in my life and I've not once had a filthy barrel sent to me. They have most certainly had a layer of factory grease and/or the signs showing that maybe 1 - 3 rounds were specifically test fired through the barrel but that's it.... With my BCM & both of my SOLGW uppers were factory test fired and sent the bullet casings with the purchase as proof. Every new barrel I get will get 1 dry patch run, then 1 wet patch with a mild degreaser which is then followed by another dry patch and then the barrel is good to go.... Even this method is a bit overkill. I've had friends and coworkers not do a thing to their new barrels other than immediately put 200-300 rounds through it and they be perfectly fine.
Most new barrels I've gotten usually had a light layer of grease or oil in them with just a hint of carbon or a little dust in them. Don't have a bore scope but when I'd looked through them in front of a bright light source, most appeared clean. I have had 1 or 2 that were dry when I got them, probably evaporation I'm guessing.
I generally will do a single pass with a brush out of a phobia for metal particle from machining followed up by a few oil saturated patches till they come out clean, then a single dry patch which I'll skip if I'm going to store it for awhile before shooting it.
It don't take much to care for them, just keep them oiled to protect from rust is all really.
@@TerminalM193 I believe that's a common practice and I appreciate them testing each barrel.
It has been a while, but as I recall, the copper-solvent bore cleaners have ammonia in them. Ammonia is very corrosive! About the only way I know to neutralize it is with lots of water. Definitely not something you want left in your bore, or on any cleaning equipment.
You're correct. Ammonia is the active ingredient in copper removers, and is exactly what ruined three of my good Sako rifles.
Sorry, but no. Unless your barrel is made from brass, ammonia did not and CANNOT ruin a steel barrel. When you say, “ammonia is very corrosive!”, I would ask, corrosive to what? Saying something is corrosive doesn’t say anything. It depends on what material it reacts with. In the case of Ammonia, it is very corrosive to copper, brass and most bronze alloys but is completely ineffective on steel. In fact, steel is extremely resistant to ammonia and is used throughout the world to pipe highly concentrated ammonia through refrigeration systems.
Fantastic informative video, will follow your advice thanks 👍🏼👍🏼👍🏼👍🏼👍🏼
Listen to these old timers! so much wisdom, not only with guns! but life and history
