I agree on checking into the regulation as well. I would imagine that you would be allowed any of the .22's, but the extra knowledge is only a phone call away.

Also, maybe I didn't see it written or maybe it simply wasn't, but what kind of yardages are you going to be dealing with on your hunts? I would think you could possibly shy away from some of the 400 yard cals. if you're only dealing with much shorter distances.

I'm personaly a fan of the .223
