My brother just pick up a new rifle and the LGS suggested a break-in procedure scheduled shooting and cleanings. Since I'll be picking up my RAR next week, I was wondering what everyone does with a new gun. I've just gone out and shot it, after cleaning up all the facotry gunk.

run a patch through the bore, then make sure you have good (read light coat) lubrication of moving parts. Go shoot.

p.s. I would not shoot a new gun I have not disassembled and inspected my self.

Clean the gun, shoot the thing, get some copper solvent, I wouldnt worry about any stupid break in precedure, never anything special with my Rem 700 and its a submoa shooter

I agree with all of the above. Clean it, inspect it and then just shoot it. I've read the Marines manual on breaking in an M24. With their job, I can see the precautions, but for my purposes I treat my rifles the same as my handguns.

I will swab out the bore every 5 shots,I do think it makes a difference, most of the rifles I have done this too have excellent performance. good luc!

I read the pros and cons, but I have never gone with the long and labor intensive break in proceedures and just dont feel or see the need.

Could be wrong, have been before, but that is my take on the subject.

My current RUGER Hawkeye, a stainless 300 win mag has provided me 100yd groups of 5/8" at a touch over 3300fps with a 165gr Nosler Partition. This with a 24" barrel.

Good enough for me!

Not bashing your theory, but I think it may have something to do with if you are that serious about group size, you probably didn't go out and buy a $100 rifle did you?

I usually just clean, lube and shoot, but when I got my Armalite AR-10 with a stainless match grade barrel I went ahead and did their break-in procedure. It really wasn't that much of a hassle to do.

I did as much internet reseach as I could on the subject. It looks like the biggest break in issue is that the rifling will have burrs on it that will scrap off copper from the jackets. These burrs will eventually smooth out but the first rounds of the gun will deposit copper into the barrel and the break in theories are just too make it easier to clean later on by minimizing this build up copper. I cleaned my gun, the 700 in .223, with nothing but a bore snake for the first couple hundred rounds (300 or so) and eventually I bought a rod long enough and some copper solvent (sweets 7.62). The gun still shoots great and if it wasnt for the human factor, I'm sure it could put 1 bullet on top of another, with the human factor though, I've seen some very tight 3 shot groups.

Well My Marlin X7 was a $250 rifle, I bought it to be a truck gun.
I NEVER do "Break-in", and it will Seriously shoot JUST off MOA @ 1,000 yards with TNT bullets.....


Break-in,
As it is touted, is accelerated wear, in order to "smooth" tooling marks from the bore. Very few of us have a bore scope. Even fewer of us have a way of "Catching" bullets without deforming them. So many "decide" that a bore needs some love, because of the amount of visible copper in the bore.
I find it humorous that you could ONLY smooth things out if the bore is squeeky-clean. As if somehow the jacket residue stops all wear.... Which MUST mean that no-one should ever clean a barrel, because then they will never wear it out....Right?

You won't hurt the barrel if you DO a break-in, you won't hurt the barrel if you DON'T do a break-in. So do what lets you sleep at night.

Clean bore after each of the first three shots, then clean after every 3 shots until you shoot a box.

Maybe I am old fashioned but my break in procedure is clean the barrel fire one round clean again fire 5 rounds clean again fire 20 rounds clean again and then fire as I wish. This is because guns were not made to tight tolerances years ago and barrels often had burrs from the rifleing being cut. Not so much any more but it cannot hurt.
