The first step to firing a firearm of any sort is igniting the propellant. The earliest firearms were hand cannons, which were simple closed tubes.There was a small aperture, the "touchhole", drilled in the closed end of the tube, leading to the main powder charge.
The primer's explosive charge is based on the amount of ignition energy required by the cartridge design; a standard primer would be used for smaller charges or faster-burning powders, while a magnum primer would be used for the larger charges or slower-burning powders used with large cartridges or heavy charges. Rifle, large and magnum primers ...
In these large cartridges a silk cord becket runs up the centre with a loop at the top for handling. [5] For quick-firing guns the charge is contained in a brass case to which is fitted a primer for igniting the charge.

Beginning in the 1860s, early metallic cartridges (e. g. for the Montigny mitrailleuse [15] or the Snider–Enfield rifle [16]) were produced similarly to the paper cartridges, with sides made from thick paper, but with copper (later brass) foil supporting the base of the cartridge and some more details in it holding the primer.
