I've used Winchester Fail-Safes (then called 'Black Talon') and Ballistic Silvertips, on deer. The exit wounds were drastically different--the BT/FS was maybe 3/4ths of an inch wide, and one of the BTs had an exit wound that was 1 1/2" wide x 4" long . . . the other didn't exit, as it shattered the spinal column and broke apart.

None of the deer went more than 40 yards. One of the BT-hit deer dropped in its tracks.
