I prefer the marlin 30-30 just because im comfortable with it and it is sufficient, that is if its under 200 yards... I also prefer lever guns because I feel I can rack the action faster than a bolt. Yet again as they have all said choose whats comfortable and ofcourse what you shoot well with. Any of those guns will kill it its just a matter of shot placement, if you feel you need to hit it with a 7mm than do it, but if you can do the same with a 30-30 then take the lesser recoil and lets face it "cooler" gun. lol
