マルティニ・ヘンリー銃の銃弾の大きさは？
In the original chambering, the rifles fired a round-nosed, tapered-head .452-inch, soft hollow-based lead bullet, wrapped in a paper patch giving a wider diameter of .460 to .469-inch; it weighed 485 grains. It was crimped in place with two cannelures (grooves on the outside neck of the case), ahead of 2 fibre card or mill board disks, a concave beeswax wad, another card disk and cotton wool filler. This sat on top of the main powder charge inside initially a rimmed brass foil cartridge, later made in drawn brass.
