Miles, I cast my 58 cal round balls outta 20 to 1 alloy, they are pretty hard, and when driven to 1988 fps, hit like a damn red brick inside of 125 yards, two deer and two DRT's so far with my 58 and round balls, the other was a nice medium sized doe at 80+ yards, she dropped from a right shoulder hit with rib cage exit as well.
