Hmph. It's converted to use a special .45 caliber, 110 metal cartridge with a 540 grain paper-patch bullet. Usual barrel length is 30 inches. This one has an extra 4. It's fitted with double set triggers, and a Vernier sight. It's marked up to twelve-hundred yards. This one shoots a mite further. It's not a lever action breech loader, I can tell you that much
