supply of .45 Colt bullets and I am unable to find anything
Just order up some bullets on-line from say Rimrock bullets or Missouri bullets or ... Bullets is one item that you don't have to worry about being 'out of stock'.
That said, I've never tried using balls in .45 Colt. Might have to give it a try sometime.
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.
