I'm surprised i haven't seen anyone else mention a 410...
410's have a lot less recoil then any other shotgun & can be used to shoot just about anything except for duck, geese, & i'm not sure i would use it for elk/moose etc...
it is a perfect gun for any small game it just might take a little more practice at shooting moving targets since it does shoot out less pellets compared to a 12/20 ga. You can even get slugs for it to shoot deer with!
Personally i use a 12 gauge but i don't mind the recoil & presently i don't have a 410...mossberg makes a real nice 410 pump...


Happy Hunting =)
