Been waiting for this one. I am an Iosso fan myself and am a firm believer that abrasives used correctly are a great tool for getting the rifle “clean”.
That last bit of carbon ring will defeat back and forth scrubbing. Find an old rod and fashion a sliding stop for it so you can set a penetration's depth. Use a one step larger brush and set the depth using a bore scope so the bristles reach the end of the neck but not into the leade of the chamber. If the chamber is a freebore type the bristles can touch the freebore area, just not into the leade. Then add a bit of abrasive and rotate the brush either by hand or even a slow drill. Even a bronze brush is OK. The chamber was cut with a reamer, and unless you run the drill for many minutes there will be no damage. Just have a look frequently with the bore scope. As soon as the ring is gone, stop. This has turned many high SD/ES barrels to low SD/ES ones, and many inaccurate hunter rifles have been returned to service.
I have used patch out for years but think that the bore tech eliminator works better. Definitely removes the copper much better. Iv check all my barrels and have no carbon rings.
I use a 308 brush in my 6.5 Creedmoor to get all the carbon ring out. I put the brush in till it stops which is right before the land then I spin the brush
Try using an oversized nylon brush. After bore cleaning with an Iosso system (I like Thorro Clean), shove a patch dripping wet with Bore Tech Carbon Remover into the top of the chamber area where the carbon ring is and let it soak there for 15-20 minutes. Tilt barrel down, Then soak an oversized nylon brush in the Bore Tech CR and spin it 20 or 30 times in that area. Carbon ring will be gone. For 6.5 bore use 7MM or 30 caliber brush.
Try an oversized nylon brush, I use an AR chamber brush in my 6.5mm and 7mm chambers, and a peice of forbytwo soaked in Boretech carbon remover over the brush. Push brush with patch on it into the chamber and leave it for 10 to 15 minutes to soak into the carbon ring. Then clean as normal. It just plain works.
Don’t over trim cases and you won’t get the carbon ring. I think you can use a max OAL case with a slight flare and an inside chamfer as a “scraper”. Once the case is formed, chamber it, and the case mouth will break up the ring. Use a borescope to check the case while chambered before flaring to make sure it’s long enough.
The probablem I often run into is my brass never grows long enough to prevent cases from being that short. The case that was inserted in the chamber was 1x fired never trimmed adg brass.
@@RobsReloading A long time ago, I used to use a brass dowel to remove the carbon ring. I learned this from Will Schumann back in the late 80s. Other than that, I never put anything down the bore other than bullets, but that was for pistols. For rifles I clean them, but only when they show signs of losing accuracy or pressure. That’s usually from the carbon ring, but I haven’t had problems with that in the rifles I shoot right now. I don’t spend forever cleaning them, and don’t worry about the copper, just a carbon. The copper always comes back within a few shots to the way it was before the cleaning.
Exactly! Running cases within .002 of max case length for YOUR chamber can boost accuracy and eliminate the carbon ring issue, just like you said. Most guys just trim to SAAMI max and will never realize this. Yes, it means you may have to trim after every firing, but well worth the effort, IMHO.
Try using a slightly oversized nylon brush just for the throat area, not the barrel lands area. Push the brush into the throat area with IOSSO on the tip and gently spin the brush (clockwise!). It gets just about all the carbon out. It’s magical stuff.
from the manufacturers website " Heavily fouled guns or those cleaned with other products should be left overnight on the first cleaning." then patch out the barrel. then do a 10 minute proof test. if color comes out on patch do another overnight cleaning. once you have done all this then a 20 minute cleaning is usually enough. anyway... i use the accelerator and the patch out and it works incredable if you follow the instructions on the bottle. glad you got it all nice and clean though.
For more effective removal do not use a brush. A tight fitting jag will be more effective with cloth patch. Add cleaning solvent first or a light oil then apply ISSO. You will notice the difference.
@@RobsReloading read the tests run on SH (or Accurate shooters forum?) about bore diameter before and after. Those BR & F class guys don’t have to worry because they replace bbls after ~1000rds no matter.
Use a Dewey jag with a patch and isso back and forth. Follow all that in the end with graphite powder all those fire cracks will fill won’t have a cold bore shot
Ive never used a paste to clean barrels but im hearing good things about this stuff so i plan to try it out. How do you get all of the iosso out of the barrel?
I have been cleaning with iosso for a few years and love it. To get the iosso out I run a few dry patches until the black starts to go away. From there I run the iosso triple action through to get the rest out. I follow up with alcohol to be sure everything is out. Then I run lock ease through to help with clean bore POI shift.
Measure the outside diameter of your fired necks and use an appropriate sized Bronze bore brush larger than that measurement on a chamber cleaning rod and you'll have no problems removing your carbon ring after a 30 minute soak of patch out or c4 product.
I have recently come to the same conclusion. I have let my LRI 6.5cm barrel soak overnight with Accelerator, Eliminator, C4, even Free All. New nylon brush and carbon in barrel looked the same. Took a fresh good quality brass brush with JB (gray stuff) on it, 2 sessions of 30 strokes, dry patches, etc, cleaned the barrel down to the steel again. Have some Iosso on the way to try, but results should be similar.
You should try Thorroclean. It's a cleaner that has Iosso in it. after about 3 sessions it will be that clean and you don't have to mix products. Not that it matters, but just saying.
Does the Iosso product have an ammonia smell to it? The reason I ask is I've been using Flitz compound for years and obtain a nearly identical results. I did read it's description on their site but value your opinion.
yup jb and kroil for neglected barrel. i clean the chamber and carbon ring every range trip and for that i use bore tech c4 carbon remover. wrap a patch around a nylon brush, 10 min soak, few twist of the brush and patch it out….
Hello rob after some thought, Inconsistent trial and error it appears the same can be achieved mixing A pinch of sea salt a cup of extra virgin oil, and some noil polish remover. Any thoughts?
Yeah man if you have the time and are willing to let things soak patch out or personally I like Bore Tech products work really good but if you want to just get in there and get it done abrasives is the way to go... yes you might shorten your barrel life but in the grand scheme of things it's not very much and the time you get back is well worth it.
I run into the same issue quite often as well, and I run those products. I too have the same issue with never having to trim cases which is the contributing factor to carbon rings. I just clean more often. Actually just saw a really good video on trimming from the owner of primal rights ruclips.net/video/H1Ah4_h7os0/видео.html

Never used iosso but I've had good luck with jb bore paste. I'm guessing they're similar.
How many rounds have you had through this barrel? That fire cracking is more than I've ever seen!

Iosso gets me a mirror like Finnish.
I would recommend a brass bore brush vs synthetic.

But are you actually examining it with a bore scope?

Hi, which jag would be best Paulclean or BoreTech ?
Have you tried a nylon brush loaded with carbon cleaner on an old rod attached to a drill? It works wonders.
Iosso and jb bore paste work great but I use it only around every 200rds because It can really screw your bore up quickly.
Do you know this based on experience? It looks like almost all of the bench rest and f class guys regularly clean with an abrasive.

I never screwed a barrel up with jb. Used it a lot in my 6ppc’s. Many different barrels.
Use it sparingly and not often.
@@RobsReloading They also replace barrels regularly.
Use a Dewey jag with a patch and isso back and forth. Follow all that in the end with graphite powder all those fire cracks will fill won’t have a cold bore shot

hi, did you use the iosso Blue Brush with the bore cleaner paste ?
JB bore paste, also very good, now your cleaning properly
On your first go with Iosso, how many strokes and did you apply it directly to the brush?
Thiughts on using boron nitride after this type o cleaning?
I have recently come to the same conclusion. I have let my LRI 6.5cm barrel soak overnight with Accelerator, Eliminator, C4, even Free All. New nylon brush and carbon in barrel looked the same.

Used to clean with iosso bore cleaner paste. They also have lubricater cleaner based on plants that don't freeze in lower temperatures.
You should try Thorroclean. It's a cleaner that has Iosso in it. after about 3 sessions it will be that clean and you don't have to mix products. Not that it matters, but just saying.
You don’t need anything more than the accelerator and the foam cleaner.
How many shot since this barrel was cleaned?
Does the Iosso product have an ammonia smell to it? The reason I ask is I've been using Flitz compound for years and obtain a nearly identical results. I did read it's description on their site but value your opinion.
I did not notice any significant odor from the iosso.
Probably alot of copper because the b14 is a chrome lined barrel not stainless
Use Kroil before using Iosso bore cleaner, or better yet, JB bore paste and magical things happen.
yup jb and kroil for neglected barrel. i clean the chamber and carbon ring every range trip and for that i use bore tech c4 carbon remover. wrap a patch around a nylon brush, 10 min soak, few twist of the brush and patch it out….
I know you were having accuracy issues with this rifle. Shooting video with the cleaned rifle this weekend?
Upcoming plans are a load work up with h1000. Not this weekend however. Maybe next!
Hello rob after some thought, Inconsistent trial and error it appears the same can be achieved mixing A pinch of sea salt a cup of extra virgin oil, and some noil polish remover. Any thoughts?
So which is better , Iosso or JB?
have you tried carb out ?
How did it shoot.
How does this compare to flintz ?
Yeah man if you have the time and are willing to let things soak patch out or personally I like Bore Tech products work really good but if you want to just get in there and get it done abrasives is the way to go... yes you might shorten your barrel life but in the grand scheme of things it's not very much and the time you get back is well worth it.
Bronze brush and turtle wax chrome polish.
Can you get a carbon ring from shooting factory ammo?
Yes. This has nothing to do with reloading. All rifles could build up a carbon ring.
Just use a 7mm nylon brush and non-bearing rod and work on that carbon ring area.
Use a brass brush instead of nylon.
👍
I run into the same issue quite often as well, and I run those products. I too have the same issue with never having to trim cases which is the contributing factor to carbon rings. I just clean more often.
