If anyone wonders the effectiveness of a 54 round ball check out the pictures! The doe was hit at 30 yards with 70 grains FF Goex and hit broadside. The roundball went through the rib cage on left side, through heart/ lungs, through rib cage on right side and stopped just under the skin on the right side. I hand cast my own balls and this one weighed 222 grains when poured. After the recovery it weighed 220.5 grains with a nice mushroom shape. The deer went about 50 yards. The patch I recovered also from the same shot.
