The mail-order division was started quite modestly later in 1977, with a small offering of ‘hand-made’ 8mm Japanese pistol ammunition and 25 Remington rifle ammunition. In 1980, Midway received the first shipment of what was to be a total production run of 500,000 rounds of 8mm Nambu brass, produced by B.E.L.L. Labs of Chicago. [ 2 ]
The primers for the cartridges were non-corrosive because the M1 carbine's gas-system would have fouled or corroded if standard corrosive primers were used. It only came in Grade R ("Rifle") because the M1 Carbine was semi-automatic only, dispensing with the use for Grade 2 for an automatic weapon.
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.
In C.I.P.-regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers. This means that 7.62×54mmR-chambered arms in C.I.P.-regulated countries are currently (2014) proof tested at 487.50 MPa (70,706 psi) PE piezo pressure.
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. This case is inserted into the gun, and when fired slightly expands and tightly fits the chamber of the gun, thus acting as an ...
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 ...
CCI (Cascade Cartridge Inc.), based in Lewiston, Idaho, manufactures rimfire ammunition, centerfire handgun ammunition, and primers for reloaders and industrial ammunition production. CCI made the first mini-mag rimfire ammunition in 1963, and in 1975 developed the Stinger, a high velocity .22 Long Rifle product.
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 ...
