Well I can't recommend just one
Getting old and knew hunters who used one of some 15 calibers on deer.
Seems the common denominator was they practiced and knew how to shoot. Not the caliber especially.
Remember getting kidded by a group of young buddies using the newer bolt action guns and I was using an old lever action rifle.
Of course, I was a one gun rifleman then, and I'd drop the deer on the spot. Had a hard time becoming a two rifle deer hunter.
Let's see. $800 X 15 equals ..... That number is just too high for me to compute.
