Why sure - 20 gauge flint rifle, .600 patched ball, 70 grs Swiss 1-1/2 Fg, estimated vel 1200 fps. I was nicely hidden behind an overturned tree stump and the fallow deer came to about 50 yards away peering suspiciously in my direction. At the shot he was fully face on. When he lifted his head the ball took him at the base of the throat and nearly made exit at his south end, traveling end-to-end through lungs, top of heart, diaphragm and most of the paunch. He tottered sideways for maybe half a step and keeled over with hardly a twitch. And no meat lost, either... ;-)
