Cartridge (firearms) - Reloading

Reloading

Some shooting enthusiasts reload their fired brass cases and plastic, paper, or brass shotgun shells. By using a press and a set of dies, one can reshape, deprime, reprime, recharge the case with gunpowder, and seat and crimp a new bullet (or shot charge) in place. One can do this at about half the cost of purchasing factory ammunition partly because the case represents a significant portion of the total cost of a round. Reloading also allows one to use different weights and shapes of bullets, as well as varying the powder type and charge, which affects accuracy and power. Enthusiasts usually only reload boxer primed cases as this reloading process is more easily automated than Berdan priming is.
