RE: Barrel break-in...fact or fiction???
Nomercy, I find in my custom barrels, it depended on the reamer job. Most of my break in occured at the thoat area for custom rifles. But my custom barrels are usually on barrel burners.
There are times where I find break in a waste of time. No matter what, the barrel is so rough, your not going to get the desired results. You can usually tell this after cleaning every round for 10 rounds. If it is still heavily coppered, I bet you that barrel ain't ever going to break in to be a smooth cleaner. Doesn't mean it won't be a good shooter.
