5 rnd mags won't cut it in some states. If the limit on big game is 5 rnds and you have a 5 rnd mag, you actually have the option for 6 rounds (one in battery). At least, this is how it was in Virginia (don't ask me how I know this to be true). If you could put in a follower that only allowed 4 rounds, you'd be GTG.
