Yes this is a very easy rechamber but why. The performance difference is minor and the 222 is easy to load. If economy is the reason, just reload the 222.. You will many times find the ammo you load if tailored for the rifle will outshoot the factory ammo.. Of course this could just be the ramblings of a diehard triple deuce lover.. But as I keep tell my lovely wife, 'I have cut back!! I'm down to just the minimum number of 222's I need, only 4.'. Yeah, I know, she doesn't really believe me either.... Good luck with the rifle..
