With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers.

Maynard's new system still required the musket's powder and Minié ball to be loaded conventionally into the barrel, but the tape system meant that the percussion cap no longer needed to be manually loaded onto the percussion lock's nipple.
With the addition of a grit such as boron carbide (in a modified formulation given as 70% KClO 3, 19% red phosphorus, 3% sulfur, 3% chalk, and 5% boron carbide by weight), Armstrong's mixture has been considered for use in firearm primers. [5] This use as primer for artillery propellants may have been Armstrong's original purpose. [6]

The .378 Weatherby generates considerable free recoil with full-power loads, for an average of 72 ft·lbf from a 9 lb rifle. This compares to 23 ft·lbf from a rifle chambered for .30-06 Springfield or 44 ft·lbf for the .375 H&H Magnum. However, the .458 Winchester Magnum generates 78 ft·lbf and the .458 Lott produces 86 ft·lbf of free ...
