Got two whitetails this fall, a small eight point with a 30-30 Winchester carbine, and a doe with my Bighorn Armory 460 S&W. Both bullets cast of COWW and water dropped, gas checked, powder coated with Harbor Freight cheapo powder. The 30-30 loaded with 29 gr IMR 3031, not chronoed but pushing 2000 fps. The 460 shooting the same set up with a 315 gr bullet at close to 2100 fps. Both deer died, (the 460 doe certainly deader) , neither bullet recovered (well, duh)...no leading observed.
