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.
A large or small pistol primer is used. [7] [8] The CIP rulings indicate a maximum pressure of 230 MPa (33,000 psi). In CIP-regulated countries, every pistol/cartridge combination is required to be proofed at 130% of this maximum CIP pressure to certify for sale to consumers. [9]
The 9×23mm Winchester is a pistol cartridge developed as a joint venture by Winchester Ammunition and Colt's Manufacturing Company. [2] The 9×23mm Winchester has a convoluted development history, but was commercially introduced by Winchester in 1996.
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 ...
Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
A small primer pocket replaced the large primer pocket. This allowed the use of small pistol magnum or small rifle primers and helped control primer flow. The final improvement came with the increased thickness of the cartridge case wall from the web area up to the beginning of the shoulder. This created a cartridge case stronger than the .45 ...
A small rifle primer .308 Winchester case is first cut down then resized to .45 ACP specifications, then primed with a small rifle primer as opposed to using the lower pressure pistol primer. Using the higher pressure small rifle primer with .308 Winchester brass designed to withstand higher pressure rifle charges gives this .45 ACP wildcat a ...
Small arms ammunition pressure testing is used to establish standards for maximum average peak pressures of chamberings, as well as determining the safety of particular loads for the purposes of new load development. In metallic cartridges, peak pressure can vary based on propellant used, primers used, charge weight, projectile type, projectile ...
