In firearms and artillery, the primer (/ ˈ p r aɪ m ər /) is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer ...
Announced to the public in early 1996 at an NRA convention, the 9×23mm Winchester cartridge was claimed to have the lowest recoiling load and still qualify for Major Power Factor designation in the IPSC. [2] [4] The IPSC Power Factor (PF) is equal to bullet weight in grains times muzzle velocity divided by 1,000. A PF of at least 175 was ...
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 ...
Winchester was a leading designer of rifle ammunition throughout its existence and has been responsible for some of the most successful cartridges ever introduced, including the .44-40 WCF (Winchester Center Fire), the .30 WCF (.30-30), the .50 BMG, the .270 Winchester, the .308 Winchester, the .243 Winchester, the .22 WMR (.22 Magnum), the ...
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The nomenclature of Spencer cartridges was unique. Unlike later cartridges such as the .44-40 Winchester and .45-70, where the first number indicated caliber and the second the charge weight, the .56-56 refers solely to the case. The first 56 is the diameter of the case at the base .56 inches (14.2 mm), measured just past the rim, and the ...
The third book in the Yarros’ “Empyrean” series comes out in January from Entangled Publishing. The follow-up to “Fourth Wing” and “Iron Flame” swaps Basgiath War College lessons for ...
The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. [3] The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi ...
