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 ...
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above those expected in actual use, demonstrating safety and design margin.
In the classic division a choice can be made between up to a 10-shot capacity 1911 with minor scoring (e.g. 9×19mm) or up to an eight-shot capacity 1911 with major scoring (e.g. .40 S&W or .45 ACP). In the revolver division major scoring can be achieved with a 9 mm bullet diameter, but with a power factor of 170.
The German Armed Forces Badge for Weapons Proficiency (German: Schützenschnur) is a decoration of the Bundeswehr, the armed forces of the Federal Republic of Germany.. The decoration is awarded to German military personnel of all grades but is only allowed to be worn by enlisted members.
[12] [13] Raising the sight line 48.5 to 66 mm (1.9 to 2.6 in) over the bore axis, introduces an inherent parallax problem as the projectile path crosses the horizontal sighting plane twice. The point closest to the gun occurs while the bullet is climbing through the line of sight and is called the near zero.
Black Talon is a brand of hollow-point pistol and rifle ammunition introduced in 1991 by Winchester, primarily intended for law enforcement and personal defense use.Black Talon rounds were known for the unique construction of the bullet and its sharp petal shape after expansion following impact with tissue or other wet media.
