Rifle Barrel Break-In
 

Can someone give me some info on how to break-in a rifle barrel? I appreciate it.

If you mean like a freshly rebuilt engine break in period, there is none for a rifle. Just buy some good quality factory ammo and start shooting. Simple as that. Maybe run a cleaning rod throgh the barrel first to get rid of any residue or factory oils still in the barrel.

It depends on the rifle, barrel and what you're going to use the rifle for.

The process I use is to fire three rounds, clean the barrel, fire three more, clean, fire three, clean. Then fire five, clean, and repeat three more times. Then fire 12, clean and repeat three or four more times.

For a new high-end match-grade or sniper rifle, clean it after every single shot for about 100 rounds or so. For a plinker, you might not worry about it at all -- just have fun

bkt hit the nail on the head. It depends on the rifle and everything else.

Sometimes the manual will give you a good break in method for you to use.

As bkt also said, sometimes you don't need to either. I haven't done it on any of my rifles and they all shoot fine, close groups.

Some say as BKT has done. A lot of people are now saying this is not needed (no offense intended at all, I have been reading a lot about it lately). "Break in" periods would clean up minor surface irregularities that are not really present in a quality barrel anymore. If you check out benchrest.com or sniper country, no one seems to buy into it anymore. Concensus is to just shoot it, just don't heat up the barrel.

Midway Usa sells some bullet for lapping the barrel. I have yet to try them, although, there are guys I talked with that swear by them.

If you are talking about "fire lapping" a barrel with moly coated bullets, I would REALLY read up on this process. Chances are even a straight production barrel will not need it. If it's a custom or semi-custom barrel (Shilen, Lilja, Hart etc.), the manufacturer will love/ hate you. The barrels don't need it and you will likely do more bad than good so they will hate you. However you'll be buying another barrel from them at some point... All this does it essentially induce accelerated bore errosion to remove flaws that are probably not there to begin with, but then again, it's not my money. Good luck.
