That's some great advice .333. I shoot my .22 a lot in the off season just so to keep my skills sharp. It's cheap and it'll help keep you tuned up. I use a BOSS sytem on my .300 and I have a non-ported weight that I put on when I am hunting..really saves on everyones ears, mine included. At the range when zeroing however, I use the ported muzzle brake and that .300 kicks significantly less than my .270.
When I am practicing (sitting, prone, sticks) I set the gun up as it would be for hunting. Like .333 mentioned though, recoil is not nearly as big an issue when your shoulder has got some give to it.
