When the firing pin hits a brass casing, a timer sets off the gunpowder, which then forces the bullet out of the casing through the barrel of the gun and to the target. Subpar casings increase the likelihood of misfires.

Made from stamping tools called head stamps or bunters, brass casings notoriously bring inherent manufacturing challenges.
