Found this out years ago with any muzzleloader loaded with 80-90 gr of 3fg an a round ball,maxi or sabot with 40-58 guns these will kill deer .The bigger calibre add a few more yards to the shot that is .$0 or 45 cal I would say is a 75 yard gun 50 out to 150 same with 54 to 58 with 98% of hunters.Remember a bad hit is a bad hit
