You actually have to hold the cylinder in alignment with the ram when you load a 1860 Colt army revolver. If you don't, and the cylinder rotates slightly out of alignment with a ball sticking out of the chamber, the cylinder is locked and will not turn in either direction.Besides that, both the .44 Colt army and navy revolver shoots the same and uses the same ball and 25 gr. load.
I prefer to shoot my Walker Colt 44. I practice with that monster on the shooting range using the 100 yard rifle targets instead of the 20 yard pistol targets. It shoots 50 gr. powder load and shooters next to me leave when I start shooting the Walker Colt .44 because I smoke up the whole target area and they cannot see their targets.
I like peole to leave because I hate it when some inexperienced shooter is next to me fumbling around with a firearm.
