Im fine using one for deer but wouldnt recommend purchasing one ifsomeone waslooking fora new gun for deer hunting. Ihave an O-U Savage in 223 and 12 Gauge and have shot 2 deer with the 223 both using 55grn Hollow Points.

I think most people would agree that at least a 243 would be the caliber of choice, some will prob say thats not enough.
