I shoot 140 grain SST's out of a 270 WSM at 3150 fps. Most of the whitetails I've shot with that load are about 200-250 yards away.
I've gotten full penetration on every one. I generally shoot the deer just behind the shoulder. No huge wounds, typical smaller entry and larger exit. Deer generally run not more than 50 ft.
They're very accurate in my rifle.
