- Randy presents some valuable information on different aspects of what it takes to accurize a factory rifle, or build a superior custom rifle. Because of many calls and emails he delves deeply into why there are some inaccuracies with some calibers, and what needs to be done.
As well as talking about the different aspects that goes into seeing to every detail to make a rifle as accurate as possible, Randy goes over different reasons there are spec issues in certain calibers, what needs to be watched for and what can be done.
Thank you for your viewing. May you all be blessed as we have been blessed by you.

It would be invaluable for reloading if you could write a reloading manuel. Your extensive knowledge should be preserved. Thank you for sharing your vast knowledge.
I’ve watched his videos several times over and over , He always gives us pearls of knowledge . .🙏🏻👍
He can’t write a Manuel because it would make Jose jealous.
@@308dad8 haha "Dad joke"
One instance that I really appreciate RUclips. To have access to this man and his knowledge is priceless
The more explanations I hear from you, the less I take for granted that factory rifles are as they should be.
Thanks for sharing your thoughts and experience, we all appreciate your efforts!
Thank you for sharing your knowledge.
Keep the information flowing. Can't get enough.
Been reloading for 24 years and I appreciate you sharing your words of wisdom.
Soak up the knowledge everyone. We are damn lucky to have this man sharing his wisdom. He doesn't have to do this, but I'm sure glad he does!
Mr. Selby's work is outstanding. He rebarreled a 378 Weatherby for me with a Hart Barrel. When I got it home I Loaded up three rounds at -5% of estimated target load, to establish initial volumetric measurement after firing, and it shot minute of angle at 200 Yards right out of the gate with those three rounds. The load workup was a breeze from that point on. Thank you sir.
I sent my Westerner 30-06 off to Mr Selby for a Hart barrel in 25-06, trie action, bedding, and tune the trigger. Can't wait to get it back and work up loads! It will be a great time seeing what I can get it to do.
Randy you need to publish a reloading manual. You would be helping many folks for many of years to come..
I learned about this kind of situation a number of years ago. I ordered a barrel for my Encore in 30/06 Ackley
Improved from the TC custom shop. No longer in existence. Well I was having some trouble forming brass and took it to my gunsmith. He checked it and told me that the headspace was too long. He told me that the go gauge for 30/06 becomes the no go gauge for the Ackley version. Well it swallowed that gauge by about 0.015. He told me to contact a fellow who made shim kits to be placed inside the firing pin bushing that would correct the excess headspace. All has been fine ever since.
I was glad to see Randy talk about this. People need to know that this kind of thing is possible.
You are a National Treasure Randy !!!! I listen and learn from you while I'm working. Thank you for the Videos.
Precision doesn't just happen, trained hands make precision happen. And this is true for everything we attempt in life.
Great video sir you have forgotten more than me or a lot of people will ever know in their lifetime. Thank you for sharing your knowledge with us GOD BLESS
Hey sir I pray you and your family are doing great Amen 🙏
We are, thanks be to God! And may you and yours stay well and safe.
one more time you are absolutely correct . I know for me its been like talking to the wind, trying to get people to listen to the truth. The day I stop learning is the day----- well you get the point. I had part ownership in some reamers out there but my I told about my buddy who passed so I'm not sure where they went. One was a 35 whelen Ackley improved, 30-30 Ackley improved, 25 Gibbs all lost. They would have been in kemmer. I enjoy hearing common sense from you and its keeping in touch with home.
Pac-Nor (Pacific Northwest) barreling Inc. will chamber a barrel to a specific ogive of a specific bullet and land relationship. I chose a polygonal profile chambered in 260 Rem.-AI, and Hornady's 143 gn. ELD-X at my Ruger M77's 2.92" mag. length; with max. OAL measured off the ogive, and in soft contact with the lands. With this setup, I can also seat the 140 gn. Nosler Partition the same way as it has enough bearing surface and without exceeding mag. length.
Randy,
I know you detest cup and draw; but with all due respect, I believe there are exceptions, such as with milder cartridges like the 260 Rem., and... as long as you know and respect the minimum distance/ terminal velocity to stay away from- The box says 2,660 fps. max. velocity; in my 260AI, that's right @my 200 yard zero. Whenever I enter terrain with shorter ranges, I switch to the 140 gn. Nosler Partition.
Always enjoy your videos and find them very informative. Thank you.
Twenty five years ago I saw the Sierra 6.5 155gr, so I made a 6.5-06AI, and the so called smith did exactly what you said. Once I figured out what was wrong, I size them a little long. I just wish someone had made brass like Norma did
Great content..thanks for sharing your expertise ...learning a lot from you sir...thanks for taking the time to educate us.
Mr. Selby if you get a chance could you do a video sometime on how to change/ set headspacing on a 7600 Remington. I thoroughly enjoy your videos and have learned a great deal. Thank you sir
big brother Selby... that topic of posterity and integrity... of principal especially in standards of conduct in industry... has been bit of a focus of my life.... .... seems to me... .. respect for those things is one of the most important things we can do for the future of the unborn... .. for the true value of any honor we may have attributed to our own existence. I have stressed quite a lot over the years as a machinist... in wrestling with the careless psychology of others... ... I do comprehend there are circumstances where maintaining integrity in industry can be very challenging... a lot of us work a lot of hours for very little pay and in extremely dangerous circumstances.. .. the owners of most industry belittle and seek to use litmus tests to destroy their workers to validate avoiding an obligation to pay a wage and put harmony into the existence of integrity....... there were very few employers who realized it was a literal obligation to keep the land lords in check so their wages could actually serve... .... it is a great big huge topic...
There has been a great deal of media programing that psychologically predisposed our workforce to "not care"... and influences from other nations who were programed similarly but far more harshly contributed to the loss of respect for standards, integrity, and posterity in industry.... and yes, from what i can see you are most certainly right. Tolerance is a big thing you know.... I work the Oil and Gas industry..and i try to be pretty hard core for my pay range when it comes to accuracy ... i have seen some who are pretty careless... saying will it work?,, well yes it will work... but but when it comes to accuracy rifles or very high pressure vessles, or incredibly expensive components doing work that can cost over a million dollars a day if it's down.... .. posterity counts...integrity is everything... there is no room for fudging the numbers ..
failure to respect this could put a thousand people out of house and home.... and possibly get a few killed.
our job ... as far as i can see... as men...... is to take care of the unborn...to build a better world for them.. to prepare their parents to do the same, and so on.... and that is very unlikely to be done.... .. with a careless attitude when it comes to maintaining the principle of standards and integrity in industry. Day to day we get tired, we are mostly poor folk, being tempted and abused by cheap lazy careless thieves... but God... and the laws of physics he created... requires it of us... . regardless. the integrity of the working man.... is the only thing there.... for the unborn... as far as i can see.
After watching many of your videos I changed my mind on the job I wanted long ago. Instead of being a A/P aircraft/powerplant mechanic I should of been a machinist/Gunsmith just like Randy because I'm much more interested in that Field of work, Gunsmith and A/P are somewhat alike things need to be right not wrong. Maybe my next lifetime. Thanks again for helping me figure things out.
God bless the Shelby's!
Thank you sir for another great video and thank you for your time I've learned alot from you by watching your videos keep them coming please and God bless you and yours
Excellent videos.
Ms. Cathy, thank you for making these videos possible. Mr. Randy, I appreciate a man who gets straight to the point, then tells the truth. That is a mark of a man who has character. My question if you will be willing to endure one, is about drilling holes to install iron sights on my factory rifles that came without them. Would I be just as well off to level the action and clamp down in my industrial drill press to drill the holes, or should I order a purpose built jig? Is there one that you reccomend? Thank you in advance, AL from Georgia.
If you haven't alreay drilled and tapped your rifle I would take it to a reputable gunsmith; why take the chance!!
@@dukeman7595 Because the only old timey wood and walnut gunsmith that I know around these parts that did my work died. I've been trying to acquire skills and tools to pass down to my son for smaller common jobs. Not many non-ar assembler/ barrel secew on types left around here.
Another great video from the master, thank you Randy!
Thank you.
I have a Savage model 111 chambered in 25-06. I like this caliber and it likes my loads to. 100gr Nosler ballistic tips is all that has ever been shot in it. No factory rounds have been fired through it and as long as they keep making the ballistic tips that’s what I’ll shoot in if.
My friend has a Winchester model 70 chambered in 280 ACKLEY improved. He had a custom barrel made for it.
I would like to hear your thoughts on so called remage barrels or quick change barrels I would also like to hear your thoughts on carbon fiber barrels thank you I really enjoy your videos
In my limited experience Remage barrels are accurate and convenient. I have an X-Cal that I chambered myself and it shoots sub half moa. Can't say much about carbon barrels because I don't build ultralight rifles.
That would be a major, major problem you are describing Sir. Thanks.
I want to thank you for your video’s sir
You are a wise man, Sir
Back when the 270 wsm came out i bought a remington 700 cdl cambered in it. And a couple different boxes of ammo to see what it liked. Fired the 1st shot bolt was very difficult to open, tried the other brand ammo and the same thing. Back to remington it went. Sold it shortly after i got it back because that rifle wouldn't feed decent
Headspace too tight.
@@johnnash5118 he should've tried the 6.8 Western in it. Hahaha
Thank you Mr Shelby !!
bedding, cartridge case neck tension, Spherical powder and magnum primers turned my .30-06 Winchester M70 into a take driver. You're worried about a barrel that isn't quite exact in groove dimensions?...... copper foul it to a point and leave it fouled !! LOL Randy mentioned in another video about stress relieved bedding. Torque the action screws evenly yes, I use blue removable lock tite, not to crank to tight to cause stress on the action/stock. Disagree with VLD bullets and throat dimensions.... as long as the magazine will accept them and they load through the mag without hitting the ramp in the action your fine otherwise you have to use a shorter bullet. Any factory rifle I own or owned has a short throat or freebore and even short bullets can be loaded out further to reach even a eroded throat. Even a "Real" gunsmith, which Randy is and I see he takes pride in his work, is still a stickler and has his own methods. Would I rather have a tigher barrel dimensionally? I have what I have, and what I can afford. Some others can afford to pay the stickler. SAMMI? Standards.... for safety. Weatherby, has long throats, for safety. Safety is first because people are sloppy. People are sloppy with handling alot of things. That's why inspectors are necessary during construction. Using winchester brass in a WInchester? Now I heard everything. LOL LOL You build benchrest rifles too ? LOL I have Remington brass in my winchester that got me under a half an inch group.
Mr. Selby, please write a book, your knowledge needs to be on paper.
That man's book would have to be in volumes
Agreed
Really enjoy your videos thank you for sharing. You talking about the 280 ai I’m thinking of building a rifle in that caliber . I’d love to hear your thoughts on that round and 6.5 06 calibers .
Terrific portrayal of facts.
That’s right on the length sir
I use mostly Winchester brass in my rifles if I can get it
Hello Randy, great video as usual. I have a question about what I've seen over several years of loading and shooting. Why, in almost every 308 win , are the throats so long in a factory chambering. About every one of the 308 bolt guns, regardless of the manufacturer, the throats are so long that when seating for the proper bullet jump, the COL is longer than the magazine well? I've never understood this.
Again, what I've seen this in mainly is in the 308 Winchester.
This is a SAMMI issue, the reamers are made to SAMMI specs. It is not limited to the .308.
Thanks for watching.
Check out the chamber differences between Euro .22 Hornet and US .22 Hornet.
Thanks Randy- So does a factory 25-06 Remington, that want converted to 25-06 AI have to have its barrel turned, then teamed?
Or is that a better practice or safer, just teaming it out?
Thanks again for your videos Randy. You are making a difference in my reloading.
Jesus is King
Quality isn’t what it used to be Sir thank you take care.
You are the gunsmiths GUNSMITH
Heck yeah
He is talking about PT&G on the reamers and headapace guage
Are you saying PT&G is doing it correctly or 4D rentals or the barrel outlet? Since he didn’t specify we can’t really say.
@@justice1327 he is complaining about PT&G and there specs.
In your opinion, would it a good idea to get a Broughton benchrest barrel, 7mm, 5R, chambered in Remington 280 AI, Stoli Grizzly II, with a Carl Bernoski stock?
It would be a good choice.
@@TheRealGunsmith I’m sorry man, I was just having some fun, I built that very rifle fifteen years ago or so, last time I shot it at 600, last relay, it was hot, and I was putting them down range, and then it happened, target didn’t come up as fast, pits called the line, said I hit the spotter pin, I hit it four more times last time I hit it, rnd 19, the pits say that they have to change the whole target, so I took a rest to try and relax, I was on a clean, didn’t want to blow it, the target came up, scorer, didn’t say what my score was, I thought I was still waiting, when he says, the pits want to know if you’re done, I opened my eyes, said I have one more, take a long look in the scope, mirage kinda looked like same, held the same windage, let her rip, down it went, started picking up my stuff, damn if it wasn’t a seven, apparently the wind let off a little 😡 Oh well, such is highpower rifle. I have a nice little stash of JLK VLD’s, 180gr, made by the man himself, if I go back to shooting, I’ll have to shoot f- class, or br. Thanks for the videos
I think your shop is in Wyoming? Im in montana and would like to bring a unit to you for work to make sure it is accurate so that I know from there it is work I need to do in myself rather than blaiming the "unit". If im right about Wyoming where is your shop located or contact info
Maybe there are sabatours working is the ammo production that are anti- gun.
How did you know I'm about to epoxy bed my last rifle? Thanks for sharing your wisdom! (Can u believe it is a Springfield Trapdoor?)
Good shooting and thanks for watching!
Difference between 7MM mag and 7 MM 300.? Your light weight rifle when I order a rifle I’ll want ammo to match at least 500 rounds, usually try to have 1000 rounds per gun
What could I expect, to get out of a 65x55 ackley , in a tikka rifle, wanting to use on elk?
Properly loaded with 140 gr bullets, W760 powder, CCC 200, WLR or F210 primers, 3000fps.
Thanks for watching and good shooting.
Thank you sir , God bless you!
Have you seen the Kentucky Ballistics where he had a 50 cal SLAP round that must of been WAY over pressured?
Luckily he is still alive. Just thought you'd be interested.
No I haven't. I'll look for it. There are a lot of people lucky to be alive. Just got an email from a guy that blew up a rifle. Some damage to his face, but it could have been much worse!
Thanks for watching!
Do you normally full length size the brass or just bump the shoulder?
Full length sized to properly fit the rifle, see video on sizing.
Thanks for watching.
@@TheRealGunsmith Thanks!
great info, but the mike cutting in and out is annoying
What yr opinion on New 6.8 western caliber good or bad sir any good for hunting
I learned early, shooting beans through a straw out the side window of a 54 Willys at road signs! (70 yrs later, all I need is a green laser!)
I would but a manual you authored even a book on your adventures
Let's say a barrel is for a .308...Does that mean the lands are gonna be 308? Or the grooves are 308? I know very little when it comes reeming barrels and what dimensions should be for each caliber
The grooves are 0.308" and the lands are the smaller diameter that engrave the rifling into the projectile.
@@14goldmedals That's what made sense in my mind but I wasn't sure..Is there a standard height for lands do you know? Or does that differ by caliber and manufacturer?
50 Stitches Steel you got me there. Comparing recovered bullets over the decades I’ve seen a lot of variance.
The lands are .308, the groove is .300.
Thanks for watching!
@@TheRealGunsmith or vice versa
I was one of the early 6.5 Creedmoor owners over a decade ago, of which I could not chamber any factory 6.5 creedmoor Hornady into my Savage LRP bolt gun. I ended up having to polish the chamber excessively and use a lot of case lube when resizing the brass of which I pulled every bullet and reseated. And even then I ended up with stuck cases in the rifle after firing. 🤦♂️
While there is some better quality control, as mentioned, shooters are still finding some issues.
Why on earth would you keep it? I would send it back.
@@justice1327 because I knew I had planned on reloading for the caliber because at the time the 6.5 creedmoor was nearly a wildcat lol. Hard to believe I know. Soon as I resized my own brass, trimmed to length, and chamfered it my problems went away. I still have the rifle and it is has proven to be a most incredibly accurate stick. 2300 rounds on it to date and still shoots sub Moa and rings steel at ease. Glad I kept it.
@@chadrides914 Glad to know the rest of the story and that it worked out.
@@justice1327 yep, but for some reason factory ammo would not chamber and if it did chamber the round would then get stuck. I don’t for a fact known if the problem was the brass dimensions or the chamber dimensions. All I know now is it works and works really well. 2730 FPS 130 gr Berger’s all day long pow ping 👊
Who doesn’t have the wrong gauges? If you won’t tell us who is using the wrong gauges. That factory ammunition way too hot you mention. I had 2 boxes that I can’t shoot in my Remington 700 in 308 Winchester. Shame because it shoots consistent but locks the bolt up. Both are from Serbia, Monarch for Academy and Privi Partisan both with PPU brass
Foreign ammo is different dimensionaly in diameter, pressure and other areas.
Thanks for watching.
Only accurate rifles are interesting. Can't remember who said that. 🤔
does the 6.5 creed brass issue apply to factory rifles also?
Yes, this is mostly where it has shown up, as stated in the video.
i cant reload. its illegal.
Where do you live where reloading is illegal?
While this guy is very knowledgeable about machining and firearms, I do tend to disagree with his mindset on terminal ballistics, bullet construction, and newer cartridges.
I wouldnt own a 6.5 creed
So you by not mentioning the company that makes the wrong go gauges, are you putting lives in jeopardy? A company can't sue you for libel if you're telling the truth
I prefer not to label the maker. This is much info on correctly made chambers, gauges. It is up to the makers to check their tools, do quality control, for their sake and safety of the consumer. I have let them know. It is up to them to correct the situation.
Thanks for watching.
CLICK BAIT be careful. he is so wrong on all you could get hurt, His gun might take his ideas but he never shows it. CLICK BAIT
?
You are a wise man, Sir
