装弹

This rifle only holds one cartridge and so must be reloaded after each shot.

这支来复枪只能装一发子,所以在每次射击都需新装。

Charlie reloaded and took aim.

新装并瞄准目标。

The earliest muzzle-loading rifles were more difficult to load than smoothbore muskets, but the invention of metallic cartridges made possible the development of breech-loading mechanisms.

最早的前装步枪装比滑膛枪困难，但金属药筒的发明促膛装装置的发展。
