Arvid Nelson was a partner in the business. The firm's first shipment was part of a defense contract to make primers using chlorate FA-70. CCI later moved on to much safer formulas for sporting ammunition. CCI provided the first reliable supply of primers for hobby reloaders. [2]
Berdan and Boxer primers are used in centerfire cartridges; the primers differ in construction. Various priming mixtures have been used in different sized primers to effect prompt ignition of the powder charge. Particles with relatively high heat capacity are required to promptly ignite smokeless powder deterrent coatings. Some priming ...
0.175" (4.45 mm) diameter small pistol primers, and a thicker or stronger metal cup small rifle version for use with higher pressure loadings in weapons with heavy firing pin impact. 0.209" (5.31 mm) diameter primers for shotgun shells and modern inline muzzleloaders , using a Boxer-type primer factory-assembled inside a tapered, flanged brass cup.
Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
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 ...
Hodgdon began marketing post-war production as spherical BL-C lot no. 2, or BL-C(2). Olin began retail distribution of Winchester-Western ball powders for pistol and shotgun loading in 1960; and Winchester-Western rifle ball powders followed in 1968. [7]
Modern primers are basically improved percussion caps with shock-sensitive chemicals (e.g. lead styphnate) enclosed in a small button-shaped capsule. In the early paper cartridges , invented not long after the percussion cap, the primer was located deep inside the cartridge just behind the bullet, requiring a very thin and elongated firing pin ...
