I don't believe it would be too much ammo. Just one question though-why take 2 .223's with you that you own, unless the other one is for someone else??? Just wondering, since you listed the guns you are taking included 2 .223's. Anyways, you should have plenty of firepower, and just make sure every gun shoots the way its suppose to. I have heard too many stories on varmint trips that people take their arsenal, and forgot to check each firearms out before the trip. Nothing like getting there, and your tool doesn't perform the way it needs to. Good luck.
