My first deer with a muzzleloader was a small 8 point,120 lbs dressed, shot with 90 grains ffg Goex and a patched round ball out of a 50 cal. Hawkins at 10 yards. If I hadn't double lunged him I might have never found him. No blood trail at all. The ball stoped just under the skin on the opposite side of the entrance. I never used them again and went to the 370 grain Maxi Ball with the same load. They are devastating on deer and leave a blood trail Stevie Wonder could follow.
