List of muzzle-loading guns

Muzzle-loading guns (as opposed to muzzle-loading mortars and howitzers) are an early type of artillery, (often field artillery, but naval artillery and siege artillery were other types of muzzleloading artillery), used before, and even for some time after, breech-loading cannon became common. Projectile (early on with shot and then later on with shells) and powder charge are loaded via the muzzle and rammed down the barrel, and then fired at the target.
