Kick drums often have legs called spurs on either side of the drum shell. These spurs are used to prevent the kick drum from rolling side to side, to prevent the drum from sliding forward as it is being played and to provide overall added stability to the drum. Casings, also known as lugs, vary in shape and size. They all serve the same purpose ...
The first references to the possible use of polymers in the manufacture of casings come from the early 1950s. One of the earliest is the patent filed by Jack W. Roske in 1950 [1] and the idea was to use a metal cup joined with a polymer shell "that will be converted to gas during the firing phase to assist in propelling the projectile and thereby permit reduction in the use of the propelling ...
The copper for the casings was acquired by scrap dealers who supposedly were using it to make brass lipstick cases. [18] They made 9×19mm Parabellum and 7.92×57mm Mauser cartridges.

Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...

Conversely, steel is more susceptible to contamination and damage so all such cases are varnished or otherwise sealed against the elements. One downside caused by the increased strength of steel in the neck of these cases (compared to the annealed neck of a brass case) is that propellant gas can blow back past the neck and leak into the chamber ...
