I just shoot them, and enjoy tight groups from the get-go.
I always agreed with the above until I helped (watched) Jerry through this break in, I'm now changed. I will try this on the next barrel I install, not for grouping improvements but the improvement in the lack of copper fowling. On the third leg of the break in he wasn't getting any copper. After the break in he fired 50 rounds (part of his post here) and didn't get any copper. I own and have installed a number of what I think are the best barrels made and I have never seen ZERO copper come out of a barrel. This is of course IMHO. Steve
