The best rifle is one that fits YOU, is in a caliber that is not only legal but you can handle the recoil, and, is accurate out to 200 yards.
To quote kmon1, there are many that will get the job done but just like there isn't one bullet in a caliber that is 'best' in all rifles of that caliber, there isn't one gun either.
Many have listed some major manufacturer's firearms and all will do the job provide:
A. it fits YOU - it's not too long, not too heavy and not to short
B. it's in a caliber that will legitimately take any whitetail you MIGHT hunt in your life out to 200 yards and in a legal caliber in that state.
C. you actually search for the store-bought ammo that is most accurate in YOUR SPECIFIC rifle and finally,
D. That you actually practice with it more than just the week before opening day.
I've guided too many hunters that brought guns that they had shot only the week before when they bought it. Please, do yourself and the game a favor and practice then practice some more.
Pay it forward - Kids are the future.
Rifles are similar to boats and young women...there's no end to how much money you can pour into them without making them any more useful.
