Rimmed cartridges use the rim to hold the (usually straight sided) cartridge in the chamber of the firearm, with the rim serving to hold the cartridge at the proper depth in the chamber—this function is called "headspacing". Because the rimmed cartridge headspaces on the rim, the case length is of less importance than with rimless cartridges.
Some cartridges, like the .470 Capstick, have what is known as a "ghost shoulder" which has a very slightly protruding shoulder, and can be viewed as a something between a bottleneck and straight-walled case. A ghost shoulder, rather than a continuous taper on the case wall, helps the cartridge to line up concentrically with the bore axis ...
Headspace positioning of rimless, rimmed, belted and straight cartridges Several different rimmed, .22 rimfire cartridges, which have a uniform forward diameter, and which have headspace on the rim, allowing any length of cartridge shorter than the maximum size to be used in the same firearm Firearms chambered for tapered rimmed cartridges like this .303 British cannot safely fire shorter ...
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 ...
Although originating from an identical preceding series of experimental cartridges, the commercial 1952 .308 Winchester and the military 1954 7.62×51mm NATO chamberings have evolved separately but remain similar enough that they can be loaded into rifles chambered for the other round, but the .308 Winchester cartridges are typically loaded to ...
Most rifle cartridges have a high load density with the appropriate powders. Rifle cartridges tend to be bottlenecked, with a wide base narrowing down to a smaller diameter, to hold a light, high-velocity bullet. These cases are designed to hold a large charge of low-density powder, for an even broader pressure curve than a magnum pistol cartridge.
The .350 Legend cartridge is engineered for deer hunters requiring a modern straight-walled cartridge. [10] It is capable of killing hogs, deer, black bears, and coyotes. With bullet weights ranging from 125 to 280 gr (8.1 to 18.1 g), the .350 Legend is a highly versatile cartridge with many end uses.
The 10mm cartridge and the 40 S&W are almost identical, but the 10mm case is longer and operates at a higher pressure. This means that you can use existing 357-Sig dies to re-form the straight-wall 10mm case into a shouldered .355" (9mm), and then the neck can be sized up to accept .358 rifle bullets.
