Paper cartridges were often coated in beeswax, lard, or tallow, which served a number of purposes.They provided some degree of water resistance, they lubricated the paper-wrapped bullet as they were pushed down the bore, they melted upon firing to mix with the powder residue and make the resulting fouling easier to remove, and they were not as hazardous to carry and handle (especially in ...
This is a list of firearm cartridges that have bullets in the 9 millimeters (0.35 in) to 9.99 millimeters (0.393 in) caliber range.. Case length refers to the round case length.
The 9mm Winchester Magnum, which is also known as the 9×29mm, is a centerfire handgun cartridge developed by Winchester in the late 1970s. The cartridge was developed to duplicate the performance of the .357 S&W Magnum in an auto-pistol cartridge. [2] The first handgun which chambered the cartridge was the Wildey pistol.
Bullet setback describes the condition when the bullet is seated deeper inside the cartridge case than it should be. In cartridges, the cannelure is a band pressed into the case which helps prevent cartridge setback when the case mouth is properly crimped onto the cannelure. [4]
Keith-Style SWC with one crimping groove and one filled lubrication groove. In practice, the bullet can be crimped over the leading band, or on the crimping groove, as desired. A variety of wadcutter types exist: HBWC (Hollow Base Wadcutter), DEWC (Double-ended wadcutters), BBWC (Beveled-Base Wadcutters), and SWC (Semi-Wadcutters). [2]
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 ...
Since a straight-walled rimless cartridge is designed to headspace off of the case mouth, this prevents the ammunition loader or manufacturer from using a heavy crimp, which is a ring pinched or "crimped" into the cartridge case, designed to lock the bullet securely in place until fired.
Small arms ammunition pressure testing is used to establish standards for maximum average peak pressures of chamberings, as well as determining the safety of particular loads for the purposes of new load development. In metallic cartridges, peak pressure can vary based on propellant used, primers used, charge weight, projectile type, projectile ...
