Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
Bullets had the manufacturer code over the Quarter number and two-digit year of production engraved on the base (e.g. Pk/2-26 is Zaklady Amunicyjne, Pocisk, 2nd Quarter of 1926). 8mm Lebel "Balle D" bullets were differenced from 7.9mm Mauser bullets by a capital letter "D" inset between the contractor code and the date (e.g. Pk/D/2-26).
[1] [2] On the other hand, the grouping displacement (the distance between the calculated group center and the intended point of aim) is a measure of accuracy. Tightness of shot groupings are calculated by measuring the maximum distance between any two bullet holes on the target (center-to-center) in length measurements such as millimeters or ...
It has a center strip of 1 ⁄ 4 inch (6 mm) of Flag Blue, bordered by 1 ⁄ 16 inch (2 mm) stripes of yellow. Equidistant from the edge and center stripes on each side are 1 ⁄ 8 inch (3 mm) stripes of yellow. The green and yellow of the ribbon represent the chevrons worn by NCOs. The central stripe of blue represents support of the United ...
Maximum point-blank range is principally a function of a cartridge's external ballistics and target size: high-velocity rounds have long point-blank ranges, while slow rounds have much shorter point-blank ranges. Target size determines how far above and below the line of sight a projectile's trajectory may deviate.
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 ...
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.
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 ...
