When old men talk it’s wise to listen. I feel like I need to take notes listening to this guy.
I save his videos and study them 2 or 3 times he has so much knowledge
Yeah and lots of coffee to keep me from falling asleep.
Old does not equal wisdom
@@darbybyebee2851 yeah I bet you know more than someone that has done this his whole life if you don't want to gain any knowledge don't watch his videos simple as that.
He knows his stuff. He has forgot more than I’ll ever know
I love the setting of this video man, not only do I get to learn, i actually feel like I'm sitting down with one of my elders. It may not seem like much to some but there is nothing better than sitting with your elders and learning from the true experience they have accumulated threw their years! Much respect and God bless.
Thank-you for that info sir
Randy is my neighbor and he's the real deal, without question and an honest, down to earth man.
I can't believe I'm only learning about this channel now. I mean......the wealth of information....quality of production and knowledge conferred upon us.......fantastic.
Thanks Chris and welcome aboard! We have Bryon Worthen of Ravenhawk Media to thank for the video production quality.
Keep watching and good shooting!
Was thinking the same thing. Gonna call him the "GHANDI" of gun smithing, this man KNOWS HIS SHIT.
Randy is one the best ! And I'm talking among the top three making videos. If you want reality you are in the right place.
Much better sources of info out there than guys that hate certain companies and are set in their ways. Top shooters prove this wrong more than ever. Go find a credible source and rely on it
@@robertbrantley1449name 1 source that's got better and more info randy give s out for free.
Nothing trumps experience, you can see the wisdom in his eyes. Thank you for posting.
Been smithing for 30 yrs. Randy is right on the money. 👍
33 yrs smithing now and this fella forgot more than I know , he knows his stuff
Always is. and Im sure that you know yours as well. So thats something to say.
do stainless steel barrels last long in 30 06?
@@rainsong73272000 rounds I'd say
@@rainsong7327you heard what Randy said in the video didn't you? He said 3006 class cartridges that were loaded to full pressure,ya can expect to get around 1000 round best accurate shots. Then it will slowly but surely degrade after that.
Way I see it, a barrel is a wear part just like brake pads on a vehicle. Sooner or later you will replace them both. How hard you choose to use them is the key variable.
You are just the man I look forward to watching videos of. I live in a small town in the deep south Mississippi. I'm also a small time gunsmith who does basic repairs and such for the public and a competitive long range shooter. With the help of some old school br shooters I have re barreled my match rifles under instructions. I have no trade school teaching not available around here. I'm self learner and have worked under a few gunsmiths before getting hired at a local gun store for basic repairs and cerakote. I have been reloading from a little kid were my father schooled me in the basics and br shooters helped me get better. This is a passion of knowledge and love of firearms and marksmanship that I don't think most people understand or care to understand any more. I won't to let you know that your world of knowledge is beyond what most will ever understand and the few of us who feel the same passion for firearms will always be grateful to people like your self who open there knowledge to us. Just remember when some say negative comments people like me and others greatly appreciate all you are doing for us.
Thanks! And keep up the good work. I learn something new every day. Good shooting!
I was just reading someones comment on their 26 Nosler losing accuracy at 415 rounds. By 700 it was not even hitting the target at 500 yards.
Great video, Sir!
It would be interesting to hear what the Army experience is with barrels. I remember shooting a 7.62 mm belt-fed Browning machine gun until the rounds were going out wildly out in every direction, completely worn out. Heat was definitely the most important factor. The barrel was white-hot. WWI MGs were water-cooled, allowing them to shoot incredible numbers of rounds in succession. . Somewhere out there, there is a cloud of data on what the engineering parameters are. I'm sure that it does not contradict what is being said here.
Good ol fashioned common sense and years of knowledge. Could listen to this man talk for hours! You speak the truth, and your videos are very informative.
I can't believe I've never seen your channel before. You're criminally under-subscribed. I'm recommending you to everyone.
Great video thank you for sharing your knowledge. I’m currently having a rifle build for a 8mm mouser. An old gunsmith is doing it and I’m helping with some of the work.Using the original action, 24” SS # 4 barrel in 30-06, Timney adjustable trigger with a muzzle brake .This is strictly a hunting rifle so it will out last me. My son will get it when I can’t hunt anymore. This is the first and probably last custom rifle I’ve ever owned.
A very interesting chat, you know your stuff young man.
Thanks for the great info! I've had questions about barrel life and you answered them.
Thanks for making this clear. I've always wondered what determines barrel life. There are a lot of people who claim to know but no one can go into detail and have as much experience as you.
i can sit with him and listen to him for hours the knowledge he has on rifles
That was amazing. Love listening to someone who has done it and seen it. Thanks so much for sharing your knowledge. God Bless!!
God bless you, too, Sir!
Great video. I think this subject is also heavily dependant on end user. A bench rest shooters version of shot out will be different to the guy ringing steels. If your starting requirements for accuracy are small then your barrel life will be as well. If you start happy with 1moa then your barrel life just extended..
Loved the smirk when he mentioned the velocity on the 6.5-300wby. I built something overbore like that, 6-284. Barrel was pretty much gone at 1000 rounds, but man it's fun. I have a 55gr varmint load for that rifle that shoots 3940fps.
sir, i can see you working at a rifle manufacturing plant sitting in your comfy arm chair telling the people what they are doing wrong..great video..you are a wealth of knowledge.
Randy, I appreciate your explanation on true barrel life and accuracy and sharing your vast knowledge! I've always enjoyed talking with you over the phone as well. People that are in the 6.5 creedmoor camp have seemed to lost all reasonable sense when touting the cartridge's capabilities. I was talking with a guy at the gun counter this past weekend while looking at a Tikka rifle. I mentioned to him that I thought it was odd that they put a 26'' barrel on a 6.5 creedmoor and a 22'' barrel on a 270 win. (I've always felt a 270 win. should have at least a 24" barrel) in the same rifle. He then proceeded to explain "it's because the creedmoor is a hotter and ballistically superior round to the 270 and that it's going to make the the 270 obsolete within a few years"-- no joke! I started to explain to him that most of my 270 loads were about at a minimum 400 fps faster than any 6.5 creedmoor loads were, but I shortly stopped explaining this because I realized there was no rational dialogue to be achieved; he had already bought into the magical power theory of the 6.5 creedmoor. I don't dislike the creedmoor, honestly, but it's not a 6.5-06, 6.5 rem mag or 264 win mag either, lets just be honest here... Keep the great content coming!
Man idk where y’all find these people but I sure find more people complaining about CM lovers than I do people thinking they are magic.
As a Tanker who used a M240 on two different guns. The main coax gun is connected to 10k rounds in a belt fed system. We alternate barrels as on gets red hot. It's using the same sighting as the main gun also shooting tracers. Never loses accuracy until the twist is wore out. 19k out.
Love the channel sir. I admire your years and experience and knowledge. Thank you for sharing it with us.
Thank you very much.
We appreciate you watching and commenting.
The Real Gunsmith just found your channel and it is great. Thank you. Do you think using the Barnes bullets that have the grooves cut in them to allow copper a place to go when the rifling cuts the bullet you would be extending the life of the barrel over shooting bullets without those grooves ?
Barrels are consumable items like tires. You want higher performance tires, they are used up faster. And your super hot rod rifle rounds also wear things faster.
The flip side is a cartridge like the 6.5 Grendel that runs only 30gr charges, a max of 52k psi and gives barrel life that seems to last forever with 123gr bullets at a modest 2450fps or so. It’s becoming my favorite cartridge because it’s so balanced.
Ding, ding, ding. I shoot a 28 Nosler that hasn't seen 1 round of factory ammo. I roll my own. In 50 rounds I found es of 6 with a great velocity that shoots sub moa. This old fart talking on the video just wants to knock anything that has any life to it past energy of a 270 lol
I love listening to someone that knows of what they speak. I've done a little gunsmithing (compared to Randy) and I've taught gunsmithing at continuing education college. I built a 6.x55 on a Mauser 98 action about the time the Creedmoor was introduced and for a while wished that I had chambered my rifle in 6.5 Creedmoor. During load development I realized that I was getting the maximum velocity for that action and my chambering because the bolt lift started getting stiff at around 2950 fps with a 120 grain bullet. The rifle shoots in the threes and has taken many feral hogs, white tail and blackbuck antelopes. There's no benefit with the particular action I used to more speed. No animal I have shot with it survived and most dropped on the spot. A few ran up to 100 feet. All of the paper I have shot died immediately. At my chosen velocity of 2775 fps I anticipate that I will not shoot the rifle enough to need a new barrel in my lifetime and I shoot far more than the average hunter. I practice throughout the year with my rifles so I am competent when it counts.
Facts!!! I agree buy a little bigger and load in the mid range or so and extend barrel life! You usually will find better accuracy at those nodes also!
Most informative video on UA-cam. Listen to this man and you will become a better hunter. He here talks base of experience and not of some marketing gimmick
Very interesting . I don't take many people at just their word on this kind of thing, but this man I believe KNOWS what he's talking about.
I agree with him 100% I load mine up and get the barrel hot thank god for gunsmiths.
I wish I could sit for days and get this information. Old knowledge on where this “new” technology comes from is awesome
and we are running out of men like him
I wish you went into more detail about barrel material. SS types, 4140 vs 4150 and even processes like nitride or chrome lining? That would be interesting to see a match barrel with a nitride treatment...
leanhard1987 may want to look at InRangeTv'a interviews with Faxon barrels.
Wonder if he was talking about inconel it is a type of stainless supposed to be a hot item right now in the cnc shops...ive only limited experience with it
Inconel is a machinist nightmare. Barrels probably priced as their weight in gold,i suspect.
@@6010babyhuey I believe he’s referring to Lothar Walther, but for some reason leaving it in the dark.
you are right on. Truth matters. Tks for saying what needs to be said.
You have "unquestionably' the best and most honest info on the. U tube. Long live and good health to you.
First of all, thanks for the information. Please continue to make these videos.
Second, I personally expect a lot more life from my barrels than 1000 rounds or less - but then I'm not looking for "hole in hole" accuracy.
I'd mentioned in another one of your videos that I didn't like the 7 mag - pretty much because of it's muzzle blast. And the worse that is, the worse all those other factors become.
I also thank you for mentioning that pressure is a factor of barrel life that seldom gets discussed.
I still like the "old and slow" cartridges.
When I was a kid, I went out and bought myself a .300 win mag, then bought a .270. I sold the .300, my favorite now is .243 followed by .223. My .270 is my big gun as I get older and smarter, my guns get smaller.
In the 1995 Ghost in the Shell movie, they talk about using high velocity ammo, eventually near the end when the main character had to fight her way out. She had an SMG and a brief case with ammo and extra barrels, every mag dump super heated the barrel and striped the rifling so the gun became unsafe. So the main character would replace the barrels.
Just something that was on a similar topic.
Thank you for sharing your years of knowledge on this subject.
I reload and have found the max load is not the best. About 10 percent under seems to work vfb the best for my accuracy. 25-06, 22-250, 6.5-55, .308. I also agree with partenion bullets for hunting from another video of yours. Thanks for sharing your knowledge.
Love the 25-06 and 308 too. Why go get the latest gimmick cartridge when cartridges from the 50’s and earlier work just fine?
My eyes and ears are wide open , when I’m before this encyclopedia of Knowledge , it’s an Honor , just to listen
The way a cartridge sits in the throat. The steep shorter angles of a .243 shoulder and the way gas pressure releases will burn barrels out quicker then a .300 Weatherby mag.
They don't burn as cleanly because of gas and powder charge release is alot dirtier then the way a .300 Wby. Does, but barrel life depends on chemistry when the blank was made on top of 100 other reasons.
The throat gets shot out in my opinion and you can't really shoot a barrel out you just shoot out reliable accuracy.
another great knowledge drop by randy. thanks for passing on what you know randy, from experience, which is hard to beat or argue with . that being said if someone is getting 2000+ round out of a barrel cambered in 6mm please let me know what super barrel they are running lol and I'm not a hater of any round , I like a lot of diff ones and feel like most have there place. I have went from 308 to 6.5 to 6mm in comp shooting and 6.5 I wouldn't take a gun to a comp with over 2000 rounds through it, 6mm about 800 to 1200 rounds though it.and on the hunting side I have took more game with my 308 then any other, but I like the 7mm bullets for hunting and if someone said you can only hunt with one caliber I would have to pick my 280AI.. I could hunt most anything with it and never feel under powered or worried it wont kill fast, hard and quick.
Randy. I love watching your videos. I cat tell you how much I learn from you. I started reloading at the age of 12. And have 38 years of experience. And I have never stopped looking for more information. Cause when you think you know everything then it’s time to quit and move on. And I will never know everything about reloading or gun building. I’m no professional such as you are. But I have only built guns for my self. With good success. My most favorite is my 6-Dasher. It has a hart barrel on it . And I love that barrel. It’s shoots more consistent than anything else i have. Creep the videos coming. There the best. And I could sit and talk with you for days. Just to listen to all your experience. I live in Utah. So not to far away. But I really appreciate what your hunting ethics are and respect for the game and the outdoors. Just because i can shoot 1000 yards don’t mean that’s how I hunt. I’m really irritated by this long range thing going on because everyone thinks that they have this great long range gun they can shoot as far as they want. And with no time spent at the range shooting to understand wind . Spin drift. I could go on but im sure you understand where im going with that. I have never shot any gam animals further than 300 yards. I fell I owe it to that animal to have a quick clean kill. Thank for all you have spoken about In your videos.

I always stay a grain under max load. I want to make my guns last as long as possible. My Savage 25-06 has never had the first factory round fired through it. I’ve loaded for it since the day my wonderful wife bought it for me fir Christmas around 12 years ago. It looks just as good today as the day she got it fir me. I had to order it special. Wood stock on it no plastic.
Through experimentation, load development, & patience - I made an old Mashburn turn from a keyholing has been to a 1 hole 3 shot group rifle @ 200m. I started with factory Remington 25-06 ammo - one box of 100 grain flatbase & one box of 120 grain boat tails. I shot the boat tails first to try & sight it in @ 25 m & nothing but keyholes. I finished that box to fireform some cases. When I switched to the 100 grain flat base factory ammo - it shredded the hole @ 25m. Moved out to 100m & shot sub moa, even while fireforming. If I forget to pack ammo to hunt with I can still use 100 grain flatbase factory ammo just fine. My go to load is 58.5 grains of H-1000 pushing a 120 grain flat base. At 2850 mv it cuts little 1/2" cloverleafs @ 200m. After 3 shots it starts to string. I keep my shots limited to 300m so I don't need more than 1 shot anyway.
The throat is eroded for the first 1/4" of the barrel's rifling. This gun will not shoot boat tails - guaranteed to keyhole the target even @ 25m. I tried boat tail handloads with proper fireformed cases. Don't give up on these old rifles & throw a barrel on it ! Try different factory ammo, bullets, & powders first. I give credit to the guy in Oklahoma who built this old wildcat in the 1950's & want to keep his work in original condition. This barrel I'm certain a gunsmith would call "shot out". I consider the shot out throat as "Weatherby Freebore" lol
Always learn something listening to this man.
It's very refreshing to listen your videos Randy! So tired of all the new gun and caliber hype. The only thing driving any of it is greed and reinventing the wheel to line their pockets. Yes, there are advancements being made but most are akin to what Mr. Ackley has already shown to work being applied to more cartridges and being re-branded as totally new. How about doing a video on what you think are the most accurate and what makes them this way?
Funny how the 6.5x47 lapua has gained a excellent reputation for barrel life. It's a high pressure cartridge and prs shooters are loving it. Large rifle vs small rifle primers have way more to do with barrel life than people realize.
Nice to listen to an older wise man talk.
My Weatherby mark v with a factory barrel, chambered in 7mm Weatherby mag, lasted around 1400 rounds before I had to rebarrel.
I have an old Sako L579 that was chambered in 243 Ackley many years ago by an old Marine I met at a gun show. He became a good friend and I knew him to shoot many, many rounds through it. He eventually sold it to me not long before he passed. I will never know how many rounds that rifle has through it but I know I put 2,800 rounds through it after he said it was shot out. It still shoots 3/8” 5 shot groups at a 100y. I can see that the rifling 3” forward of the throat is worn but it just keeps printing great groups and I keep smoking sage rats at 400-550 yards with it consistently. It is the rifle that taught me to handload and one i would never consider parting with. Sadly, I will never know how many rounds it has through it but I know it is several thousand.
Thanks for sharing your years of real world experience.
Very informative. Thank you for sharing your wisdom.
Guys should listen to Randy; he knows what he is talking about. I love listening to him. What a great man, shooter and hunter! God bless you and your wife Randy!
Thank you so much! Thanks for the kind comments, and for watching. God bless you and yours, keep you safe and well.
I learned a good amount from this.
Randy, my son and I shot with Boots Obermeyer and Jack Krieger. They both counted rounds. Jack once said in a highpower class that hammer forged barrels had to much stress in them and something would pop and give way after 1500 rounds. They both single pointed their best barrels to keep the stress down. I remember Boots telling me he had 9,000 rounds in a 308 stainless barrel before it gave up and 8000 in a chrome moly. He shot Palma with both those barrels so it did not heat the barrels too much. Both he and Jack pooled their orders for barrel steel and then they checked for incursions before they would accept the order.
I cant argue with anything you have said, I would add, that with higher pressures comes higher heat. I believe that higher heat conditions are the most damaging factor and that can occur from shooting multiple rounds as you stated but it also occurs with shooting far more fewer rounds at higher pressures. Pressure can equal higher temps. I have a 308 that was built in the 1960's and it to this day shoots 1/2" and 1" groups depending on the load. This gun I purchased new and know that it has had 5500 rounds thru the barrel. I have always been extremely aware of heat buildup and did my best to prevent it. I also believe proper barrel maintenance thru cleaning is extremely important.
Thanks for sharing your videos and keep them coming please.
I've had the barrel cut and re chambered on several rifles. Just enough to get rid of the throat erosion.
Glad i watched this video this explains why im no longer getting consistent accuracy from my old 7mm rem mag. I know i have about 2500 rounds through it. I learned how to reload and used that rifle for everything. Mostly shot paper some varmints some deer and pigs. Shot alot of those bulk 500 count speer 110 grain varmint bullets, (4 boxes) usually at high velocity. High speed and low recoil. Worked great on coyotes. Noticed i could regain some accuracy by going to heavier bullets seated slightly further out of the case. Its still Good enough for medium game hunting out to 300 yards or so. 😅 i dont need a 7mm rem mag for that though. Bought it slightly used for $450 out the door 27 years ago. Probably most people would never put that many rounds through a 7mm rem mag. Not buying multiple rifles overall probably saved me money over the years. As some people buy new rifles for certain purposes and reasons. One for deer one for varmints one for elk one for bears one for target shooting. I did however have to endure more recoil than i would like at times.
You are right, Randy, about WC 860 I used it on the 7mm STW with the 175 Nosler Partition. WOW!
I shoot PRS in my first rifle I basically used Hornady factory match ammo and got 3,500 rounds before it went from a .5 to 0.8 inch barrel. My next barrel was an X-calibur barrel same caliber and I only got 2200. My 6 GT Krieger barrel I got 2,600 rounds and now I'm running a proof research barrel, I'm at 2400 rounds and it is still shooting .4". The guys running competition 308 barrels are getting around 3,500 to 3800 rounds before the groups open up and the 223 shooters are getting about the same.
This comment section is full of derp. The 6.5 Creedmoor was designed for shooting NRA High Power rifle competition. It was intended to function with 140gr bullets, fed from a magazine in a short action. 6.5mm bore was chosen because it offered the best ballistic performance with regard to accuracy, recoil and barrel life for that sport (shooting with iron sights at 200, 300 & 600 yards).
thank you sir for sharing your extensive knowledge
Sir, I wished I'd had found your channel sooner. Thank you for the info provided.
Your talking common sense, a lot of people don’t know how to use that correctly anymore.
Brian B.... Amen & AMEN to THAT!!!
Real Gunsmith looks like and reminds me of my Dad dispensing his great knowledge.
Thank you.
Brian Blackwell Amen. Can’t tell none of this to “fan boys”. Lol you get told you don’t know what you’re talking about
That's because it isn't common anymore.
Yep and the 55 thumbs down know more than Mr. Selby, now 68, I don't think so desk jockey's. It's not just the bullet wt., but the amount of powder and type used, which causes the over pressures which takes the barrel accuracy away, the metallurgy of the barrel, how it was forged, 416, chromoly, stainless etc. I agree 100%, also the rifling groove depth and twist rate also play a role.
Bravo ! Thanks a ton for this explanation. I will take this info as gosspil. You are a fantastic speaker.
Well I know now to keep my 6.5 creedmoor plinking loads down to close to starting grain pressures, and only load up for hunting and precision. Make the most out of my barrel life before the throat erosion gets too bad.
I have a 1975 700 adl 6mm has never lost it's luster yet it's got a high round count.
I LOVE my 700 Rem 6mm, a decade or so older than yours...one of the most great cartridges unappreciated by the 'masses' :) out shoots the hell out of the one trick pony 6.5 creed :) Notice now the 6.5 being replaced by 6mm creed, and with good reason :)
Thank you sir 🙏 for this video I was thinking about getting a 6.5 Creedmoor rifle and now no way,I have a m1A in 308 and love it and fired about 4000 rounds out of it never stress it out(barrel) and its still my DMR baby,
Cold hammer forged chrome lined Kalashnikov 7.62x39 barrels are one example of barrel which has a pretty amazingly long life. When I first bought my Romanian Kalashnikov I slugged the barrel. Last year I finally surpassed 30,000rds fired through it. I slugged it again and it hasn't increased in diameter either at all, or it's such a small amount that my dial caliper which can measure 0.001" at the smallest cannot measure it. That's 30,000rds of Russian production mild steel jacketed bullets which have a very thin copper wash over the steel jacketing.
ABSOLUTELY RIGHT
I like this guy.
The average shooter will not shoot out a rifle barrel. I have a Remington Model 700 in 7X57 I bought new in 1982. The rifle with handloads will shoot 3/8 inch 3 shot groups all day long, on average the rifle is shot maybe 10 times a year ( check zero and used hunting) I've seen rifles that are 50 years old or older that still shoot 1/2 inch or less at 100 yards its all about proper barrel cleaning and not shooting the rifle til it gets hot , meaning so hot you can't hold on to it.
Agreed. The average hunter will never shoot out a barrel to the point where it loses acceptable hunting accuracy. To target shooters, barrels are a consumable.
I know a competition shooter that swaps a barrel after 1,500 rounds. That's basically one year worth of shooting for him, half a lifetime or more for a big game rifle.
It is not about the age of the rifle, it is about the number of rounds shot through it and the manner of shooting. I can buy a 1/2 moa rifle and put it in my safe for 100 years and it will still be a 1/2 moa rifle, the fact that it is 100 years old is immaterial. Randy is correct on people ignoring pressure, but barrel life is all about the number of rounds shot. One cannot compare a 1990 car with 30,000 miles with the same year and model car with 200,000 miles, same with barrel life. Loss of accuracy is caused by erosion in the throat of the rifle, which is caused by heat and pressure. This is why people "chase" the lands by extending the bullet more, to extend barrel life and accuracy.
Few points...
Barrel life is a combination of several things. The 4 most important are:
1. Peak pressure (higher = more wear)
2. Barrel temperature (higher = more wear)
3. Amount of propellant (more = more wear)
4. Bore diameter (more = less wear)
The wear has nothing to do with friction of the bullet or its peak velocity. The wear comes almost entitely from the initial high pressure, high heat, high carbon gas blasting the throat of the barrel and the first couple inches. It is like a combination torch and sandblasting type effect but just a short duration for each shot. Forcing a large, high pressure charge into a small bore means more wear. Hot steel of any type is softer and the cutting/blasting effect on the throat is enhanced. This is common sense.
I dont clean my barrels till they have a drop off in accuracy. It takes about 10-20 rounds to re-season your barrel with copper and fouling to get consistent accuracy and velocity. I shoot a 6.5 Creedmoor. It does drop off on accuracy at 1000 rounds... but then I clean it and do a full copper removal. 20 rounds later, accuracy is restored. You can do that at least 3 times. I shoot 100-300 rounds a session, usually about 150. If 6.5 Creedmoor burned up in 1000 rounds Id throw it in the trash because I'd burn a barrel every couple months. My pet load is a 140 grain bullet loaded with 42.0 grains of H4350 so I shoot it with a very full, but not 100% case capacity load and it is over book on many, but not all, reloading manuals. Still producees .75 MOA groups right at 2000 rounds. It started at .6 MOA. Expect to see about a 0.1 MOA decrease in accuracy per 800-1200 rounds fired. A barrel that starts at .5 MOA would stay sub MOA for 4000-5000 rounds if you never got it stupid hot.
Your videos are great! a lot of experience and knowledge.
Very Interesting indeed I believe that you have confirmed my own hunch only based on a few barrels on various calibers. just bought a german barrel so far so good!!
For those of you who make stupid comments and really don't seem to know too much, the 6.5 CM has basically replaced the .308 Winchester on the firing lines in both F-class and Across The Course matches, due to its light recoil, superb accuracy, ease of developing load data, and the ability to remain super-sonic at 1,000+ yards. I know that most guys have never shot a rifle beyond 100 yards, let alone 200 yards. Most of the guys in my F-class group have now abandoned the .308 for the 6.5 CM. Once my .308 barrel is toast, Bartlein will be installing a 6.5 CM on my custom F-class rig too. Sadly, there are those that do, and those who watch UA-cam in their underwear and think they're gun guys!.
I could sit here all day
One of my shooting hunting buddies has a highly accurate ruger No 1 with a Douglas air gauged crome moly 26 in barrel win 7 MM STW. Now there's a recipe for short barrel life. But it will probably last two life times. When siting it in he never shoots more than one round per minute and never more than three in a string with several minutes between strings. He probably shot 50 rounds for load development and averages 10 rounds a year for site in and actual shots taken on game. With this use, any crazy super magnum even the 6.5 -300 wetherby is a life time gun.
Very good info. I have a 6.5 CM. And it's a cheaper rifle. If I ever shoot it to where it shoots over 1" group I'll keep it and buy another. If you like a caliber keep shooting and buy another barrel or fix it. Pretty simple.
6.5 Creedmoor is consolation prize for kids who actually wanted .338LM
Best to watch this channel at 1.5 normal speed :)
Thank you for educating me on this.
I have a Savage 110- .270 pillard , with bedded recoil lug, shooting 130 grn ballistic silver tip with 57 grains of H4831sc, 3,000 fps. 5 shot group @ 7/16" groups with over 2k rounds thru it.
Will a gain twist rifled barrel extend Barrel Life?
The 6.5 Carcano had gain twist rifling, today the A10 Warthog and some 30mm guns have gain twist barrels to reduce chamber pressures and weight if I recall.
I’d be interested in seeing the cost / benefit.
Thank you so much for this video, you've answered a ton of questions for me!
Looks like there's 30 people whom are a lil pissed hearing the truth. :)
Great video- love the knowledge and experience. Thank you
Excellent information, thank you.
So when am I going to get a ten hour conversation between The Real Gunsmith and GunBlue490?
Love to be a fly on the wall, and hear those two men just discuss anything and everything
I'd suspect that there'd be some differences between them though but I'd really appreciate hearing their logic and reasoning. It'd be very interesting!
I respect both of their opinions but I suspect it'd be like a conversation between Keith and O'Conner about what makes a great hunting round.
Craig Boddington should be the moderator!
That would be awesome.
Knee Beats shin, I’d take Randy’s side in that argument.
GunBlue's are really lengthy. You got to be in the mood for a long video-lol. For less knowledgeable people seeking depth ,Randy and GunBlue do a really good job. Very practical insights. They remind you that like any business, there is marketing hype and a lot of it is horse manure. They also remind you that much on the internet is the same.LOL. They are two of my favorite guys to watch on youtube.
This is the only video I agree with, i myself had a 26" 6.5 creedmoor, button rifled barrel I loaded for, The load was 40.3gr of varget with a 130 berger hybrid going 2970fps shot prs with it accuracy fell of at 1250 rds
What's the working life of a .270 Win. factory barrel on a Ruger M77 Hawkeye? Shooting 130 grain BTSP loads doing 3,000 FPS?
Well, I understand that my Remington 700 in 308 will last longer than my Core 30 in the same caliber for obvious reasons, but the amount of people that dont understand surprises me
I have a 7 magnum sendero 2 remington, I purchased this weapon from sportsman's warehouse in southhaven, Ms.last year. I must send the weapon back to remington because the spent shell's want eject, and the weapon discharged without pulling the trigger. What's the best Round do you recomend. Thanks so much for your service!!!!!
Thank you for sharing your many years of knowledge
Thank you for all the lessons you're teaching here Mr. Selby. I'm just curious of what kind of steel the Germans are using that you mentioned in the end of this video, that make German made barrels last longer? That you said is not available in the U.S.
You have a NEW subscriber sir ,,,, I like life time knowledge and sir you have it , thank you for sharing ! 👍
You speak truth, from your heart,. I shoot short distance!!! Keep it up. ,,,,,
Great information! Thanks man.
you also have to take in the equation cleaning, powder temp and burn rate. I shot a 6.5x284 barrel out using H4350 @ 1710 rounds it shot 3/4" group. I had a new Bartlein 28" barrel put on it and have only used Vit N165 powder and religiously keep the chamber and throat clean of carbon. I have 2110 rounds on this barrel and it still shoots under 1/2" groups. Carbon will speed up the throat erosion process a lot!!!
Great video. Was watch as i cleaned a rifle. Couple of our rifles we push a little hard. 6.5x284 usually we consider swapping out the barrel around 800 to 1000. 264 win mag, 1200 rounds and still sub MOA. 6.5x284 that we use slow burning powder in barrel has a lot longer life. I have an old 70's 7mm mag never been loaded hot still kicken with the original barrel. 6.5 creed, well thats what we let the kids shoot. You push the load you buy a barrel sooner. Throat starts to look like gator skin.
Randy, how much barrel life should I expect out of a average stock factory barrel, in .300win mag firing 175gr bullet @ 3120 fps ????????
I use 3.5 gr. tite group for .224 and 8 gr. for 308. Pressure is 4,000 for .223. In bolt rifles. After shooting, the brass comes out of the rifle cooler at an indoor range than it is in when it comes out of my trunk. The brass has lasted over 50 times reloading, so far. after over 2,000 rounds, off a bench at 25 yards it will send the bullets threw the same hole.
I like this guy he gives some good info 👌
