"Seson the bore"
Well, I know this is a somewhat controversial topic, but I've always "seasoned" or "broken in" all my new rifles barrels. It probably is indeed unnecessary, but I like doing it and it's part of my traditional approach to getting a new rifle ready for the field.
I fire one shot, and run three wet patches through the bore. I do this for five shots. Then I shoot five shots and clean the bore. I do this for 20 rounds. Then I shoot 10 rounds and clean the bore. I do this for 50 rounds. While I'm doing this, I check the trigger, make sure the zero isn't wandering, and so forth. After I'm done, I do a through cleaning with brass brush and all, and then wipe the bore with Tetra Grease (be sure to wipe out all excess grease before you next shoot the gun). It takes a couple hours, to be sure, but I've never thought that a few hours at the range was time wasted. I'm just hard-headed and old-fashioned, I guess.
Anyway, the Tetra stuff seems to "season" the bore just like oil will "season" an iron frying pan, making it easier to clean. To be honest, I scoffed when I first heard this, but I have seen the results myself - even Garand and AR barrels clean up quickly and throughly.
I have friends who use similar products (Mpro7 comes to mind) with the same results.
