The .45 Colt factory load has always been a dependable Ctg. The big flat nosed 260 gr slug at 850 FPS will stop a horse or man. No Army in the world went to the .357 Mag. when it came out in 1935. The .357 loaded with a 125 gr HP is hell on thin skinned critters, no doubt. But for all around back country use the Old Colt round is hard to beat.
