I love my Marlin 336 as well.. I thought the question meant one gun for every huint..rabbits, pheasnts , wild hogs , deer etc..then that would be my 870 shotgun..
I mostly hunt in a thick swamp...for hogs and deer in Florida..my 336 Marlin is tops..
BUT ALL AROUND PUTTING MEAT ON THE TABLE..870 is my #1 choice
