I wanted a backup black powder pistol for white tail season, I'm using an inline TC Encore rifle and wanted a revolver for close range shots, 20 yards or less, for finishing or taking smaller does. A few friends have Ruger Old Armys but after doing some reseach on the net I understand they're only equivlent to a .38 revolver and I don't like the terminal balistics of a round ball. I was thinking of a Colt Walker with the largest load I could get (52 grains is the capacity I think) with a conical lead bullet that would give good expansion....any advice?
