A big round ball can have unbelievable penetration. My biggest is a .54 Leman half-stock. With it's 34" X 1 1/16" Sharon barrel I can utilize some stout charges. I once shot a 200+ lb. buck with it at the lower edge of his white throat patch, facing me. I was in an elevated position at 80 yds. The ball penetrated him ................... lengthwise, and exited under his right hind leg.

Best wishes on your quest, SRH

May God bless America and those who defend her.
