My choice is a shotgun for small game.
I don't know why but I LOVE to small game hunt a bit more than big game hunt.
Rabbits, tree rats, ducks, geese (well, waterfowl), but things of that nature.
Dove, quail, etc. I think I like it more because of hunting with friends.
I wish we still had good populations of Phesants around here.
Now for big game I bow hunt, then blackpowder. I rifle hunt some but still keep my shots within 50 -70 yds.
