I've killed herds of deer with 80 grs of Pyrodex or 777, and a 300 gr Hornady 44 cal XTP

I've only recovered one bullet that penetrated nearly three feet lengthwise through a buck, and stopped under the hide

He was 50-60 yds out, and the MV was around 1600 FPS


One shot, one kill........ It saves a lot of ammo!
