Couple of examples under 255g .45 Colt bullet.
I load 20g 4227 . So 1lb can will fill 7000/20g = 350 rounds.
I also load 8.5g of Unique. So 1lb can will fill 7000/8g = 875 rounds.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
