All the preimum barrel makers recommend a break in.
That's not really true.Most do, for sure, but there are some that don't.Here's what Hart says: "We do not believe that a break in procedure is required with our barrels." The guys at Shilen don't think it's a big deal either. And the late custom barrel maker Gale McMillan was absolutely against it.
I've done it a few times myself, but I eventually concluded the time and effort wasn't worth it for me. I just didn't see anyreal benefits. Okay, maybe copper foulingwent away sooner, but so what.My non-broken in rifles shotjust as good as the ones that were "broken in".Instead of dedicating a half day or so tediously breaking in a rifle, I now prefer to spend15 or20 minutes after each shooting session (15 to 20 shots) to throroughly cleanit.
