What are you thoughts.

I got my hand on a new savage 12LRP in 6.5 creedmoor


All my other guns I have just shot and clean with no real break-in.

What are your methods?

Shoot it a bunch, occasionally run a boresnake through, shoot it some more.

Clean it spotless, put twenty foulers down it, then test your handloads or factory ammo.

Break-in is hogwash in my opinion. Copper fouling is beneficial, especially on a brand new barrel, that has machining imperfections that the copper will fill in.

Amen.
I've never understood the "shoot one round, clean, shoot two rounds, clean, shoot three rounds, etc." school of thought. Maybe it was secretly floated by ammo/component manufacturers and it caught on....

A regimented break in procedure that requires anywhere from 5-15 cleaning with solvent within the first 100 rounds is probably a load of bs. That said, i was at the range next to a dude with a very pricey looking custom bolt (had no idea Colt produces such an item). This was literally his first outing with the rifle. Had inconsistent groups. I let me borrow my bore snake and they instantly got better.

In conclusion, the truth seems to be somewhere in the middle. Should do some very moderate cleaning within the first 20-50 rounds. i would imagine even a dry brush with a good rod or a bore snake will do the job.

but who really knows such things.

Why do some barrel makers require a break-in? I know GAP Rifles barrel break-in procedure Is a pretty pain staking process.

I've always just cleaned mine when new before the first shot then cleaned them after each of the first few range sessions.

I've heard this question beofer and my theory is that rifle manufacturers are preemptively making that statement. That way when some idiot comes a calling, "why is my sniper rifle not sniping?" the manufacturer can at least say, "did you break in your rifle as per instructions?" When in fact they probably really wanna say, "because you're probably a crappy shooter." and just don't want to say it out loud.

but that is only a theory from a skeptical/cynical person.

I'd like for someone to hand me two identical brand new rifles. Follow a "break-in" procedure on one, and not on the other. Shoot both for 200 rounds, total, and see if there is any marked difference in the two. Then maybe we could put this to rest.

for those of you who know "nobody/Larry" he is a huge AZZ wagon but the guys has literally 1000's of skins on the wall and his barrel break in procedure is stellar........

I have never done anything special to break in a center fire rifle barrel other than fire multiple rounds through it. But I do not consider myself a "shooter" but more of a "hunter" who shoots a reasonable amount so I can be an effective hunter.

Staying with the intent of this thread..... what is the consensus on "lapping a muzzleloader barrel?" If I am hijacking this post tell me and I'll withdraw the question.

I have a friend who is an outdoor write & outfitter and who is probably the most knowledgeable person I know on muzzleloading and he swears by lapping the barrels on a new muzzleloader. Mine was shooting so well before he lectured me on this subject that I never did anything..but I had shot 100's of rounds through my muzzleloader.

Just curious.

I have never even cleaned the bore before the first range session before on any of my rifles. I feel like I have 2 exceptional factory rifles as far as accuracy is concerned. I used to clean them once a year now I clean them when the groups start to open.

FWIW Frank aka lowlight did that with two rifles and reported that without serial number data one can't tell which is which.

Myth.

One barrel shoots .2 moa and another gets. .4 moa. Don't neglect to give it a good initial cleaning though.

Boom! Done, that's that.

Now someone is going to say it depends on chambering, barrel maker, blah, blah.

I've never done it. When I get a new rifle or used, I clean it then shoot fowler loads and I'm off to the races. A lot of the time the fowler loads group fine and sometimes they slowly tighten up. I don't know why or what does it but I know it's ready after 20 rounds.

i would say if you wanted to know with statistical certainty a bunch of factors are going to come into play. I would say if you took two guns from the same manufacturing process (regardless of which one) that it would take a lot of data to prove a difference. I would say at a minimum a, a good way to measure (however you choose to measure), 100+ data points, and identical conditions.

The problem is the all three of those elements would be suspect

Lots of misinformation and guesswork goes around about barrel break-in. If you know how to use a bore-scope and understand a bit about metallurgy, it's not so mysterious.

Some barrels benefit more from a careful break-in than others, all do to some extent of another.

"Experts" who have never taken proper care of a new barrel and get good accuracy have no way of knowing how much better accuracy they might have gotten with a barrel break-in.

Copper is beneficial in the barrel the same way that lead is, which is to say it is not really beneficial at all.


Kind regards, charlesb

You're really breaking in the throat rifling where the reamer stopped. I always follow the manufacturer...reason why is a buddy had a problem with a barrel and they wanted the stub and how it was broken in. If it wasn't broke in to their recommendation he would've had problems getting them to replace.

One thing to keep in mind is what does a barrel manufacturer have to gain by having you clean/break-in a gun? It's not like they are in the cleaning supply or patch business. Just something to think about.

Keep in mind the game I play a .5 moa gun is a great tomato stake....I will say do what works for you but don't judge others on how they do it.

I agree with you there

it's really no mystery if you understand metallurgy

it's the same reason why engine motors have a break-in period

I got into this sport many moons ago shooting benchrest
at least 1000 rds a week for over 6 years so i know what potential you can exact out of a
barrel if you take time

met a gunsmith at Gunmasters in Plano, I think his name is Mike
he and I agreed on a lot of things and he even gave me a tip
that I've never thought of and the results were astounding

some barrels don't need break-in cause they lapped it from the maker;
those you just shoot

one of the manufacturer that I deal with uses Bartlein barrels and they recommend break-in procedures

DPMS SASS rifle comes with a Break-In procedure for their fine barrels

you don't have to break it in, but if you understand what those burrs inside a barrel
do,,, it may change your mind

My next rifle I am going to try something different on. Breakin loads using CFE223. Think about it, no copper fouling to clean out between shots or very little. Wish I had a bore scope to see inside the barrel


lf the saying "Liar, Liar your pants on fire" were true
Mainstream news might be fun to watch

The guys at Bartlien will tell you that the barrel doesn't need anything it's the throat area that is being broken in. They say even that will depend on the person cutting the chamber and their practices plus tooling quality.
