Hmm thanks for the advice. I am trying to get the rifle to the range a couple times a week and shoot about 12-15 rounds a time in it. Then about the same amount with at least one other calibre.
Another thing I'd suggest is to wait a few minutes between shots. Not only does it keep the barrel from heating up quite as quickly, it lets the shoulder recover so subsequent "kicks" are on a recovered shoulder rather than a recently whopped shoulder. Its amazing what 3-5 minutes will do for you. FWIW, I notice this also with very heavy recoiling handguns.
I'll often take a .22 rimfire and some handguns along with the centerfire. Shoot the centerfire only when the barrel is cool and shoot the others while I wait.
