Revolver ammo (in general) has a rim that is wider than the casing to hold the cartridge in place within the rotating cylinder (prevents it from falling through the hole). Semi-auto ammo (in general) is not rimmed wider than the casing. Rather, it has an extractor groove. That groove gives an appearance of a rim behind it, but the rim is often the same diameter as the rest of the casing.C-dub wrote:It's not the same stuff?John Galt wrote:How does the ammo compare to 44 mag revolver ammo?
So, in theory, the ammo for the semi-auto would fall through the holes in the cylinder of a similarly-sized revolver.
