The cylindro-conical shape of the Minié ball also meant that the smaller-diameter but longer .58 caliber Minié ball had roughly the same amount of lead and weight as the larger .69 round ball. While the caliber was reduced, the overall length of the barrel was not.
Various types of Minié balls. The four on the right are provided with Tamisier ball grooves for aerodynamic stability. James H. Burton's 1855 Minié ball design (.58 caliber, 500 grains) from the Harpers Ferry Armory. The Minié ball, or Minie ball, is a type of hollow-based bullet designed by Claude-Étienne Minié for muzzle-loaded, rifled ...
Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge shotgun's inner bore diameter to weigh 1 pound (453.6 g). [5] The term is related to the measurement of cannons, which were also measured by the weight of their iron round shot; an eight-pounder would fire an 8-pound (3.6 kg) ball. Therefore, a 12 gauge ...
Also, the Minié Ball, being conical and longer than it was broad, had much more mass than a round ball of the same caliber. A smaller caliber Minié ball could be used to provide as much mass on target as the larger .69 caliber round ball. For these reasons, the Model 1842 was the last .69 caliber musket. The Army later standardized on the .58 ...
The Remington Army cartridge-conversions were the first large-caliber cartridge revolvers available, beating even Smith & Wesson's .44 American to market by nearly two years. Due to the large volume of these pistols, individual gunsmiths also produced cartridge conversions (from cap and ball versions) in a variety of calibers such as .44-40 and ...
The Model 1865 fired a rimfire .58-60-500 cartridge (.58 inch 500-grain (32 g) bullet, 60 grains (3.9 g) of black powder), the caliber matching that of the Civil War Minié ball, which was originally used in these rifles. The Model 1865 quickly became obsolete, and most of them were sold in the 1870s to several American arms dealers.
