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 ...
The cost per round of wax bullets is low as primers can be purchased for under US$ 2.00 per 100 in case lots and as the wax itself can be reused. Reloading is very quick, and requires minimal equipment: a decapper tool to knock out the used primer and a priming tool. With these, loading 50 rounds of wax bullets will take under ten minutes.
The .375 SOCOM is a fairly new cartridge, designed by Tromix in 2013. Taking a .458 SOCOM cartridge case and sizing the neck down to .375 caliber, resulted in a hard hitting AR-15 compatible cartridge, that has a considerable velocity and range advantage over the .458 SOCOM as well as other big bore AR-15 cartridges.
A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
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 ...
Cartridges of the World is a comprehensive guide to firearm cartridges. The reference series is written by Frank C. Barnes . The latest version of the book is its 17th edition, published in 2022, and edited by W. Todd Woodard.
Since the loud report and flash of ignition, and not the projection of a bullet, is the goal of the cartridge, it can be used in firearms with different bore sizes. These cartridges can be loaded with different charges, ranging from quarter-load charges for indoor scenes and scenes around animals, up to full-load charges for outdoor firing. [1]
ICL cartridges are wildcats based on conventional cases in use at the time. They feature a 45 degree shoulder [3] and the sides are straightened out compared to the parent cartridge. Most of the cartridges are considered improved cartridges since they simply create more powder space while maintaining the same caliber as the parent cartridge ...
