A series of individual 1/1,000,000-second exposures showing shotgun firing shots and wadding separation. In shotgun shells, the wadding is actually a semi-flexible cup-shaped sabot designed to hold numerous much smaller-diameter sub-projectiles (i.e. shots), and is launched out together as one payload-carrying projectile.

In bolt-action, lever-action, pump-action, semi-automatic, and fully automatic firearms, the extractor typically works in conjunction with a separate ...

Blank cartridges frequently contain a paper, wood or plastic plug called a wad that seals the powder in the case. This wad can cause severe penetrating wounds at close range and bruising at medium ranges. There is also "muzzle blast" – a jet of hot, expanding gas expelled at extremely high velocity from the muzzle of the firearm.

In smooth bore muskets and most rifles used prior to cartridges being introduced in the mid-to late nineteenth century, wadding ...
