A box of .38 Special (9.1 mm) cartridges that have 148-grain (9.6 g) bullets. Grains are commonly used to measure the mass of bullets and propellants. [11] [12] In archery, the grain is the standard unit used to weigh arrows. [13] In North America, the hardness of water is often measured in grains per U.S. gallon (gpg) of calcium carbonate ...
A bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. ... 115-grain (7.5 g) – FMJBT; 130-grain (8.4 g) – soft point;
The heaviest commercially loaded ammo available for the 7mm is 195 grains, [6] while the .30-06 Springfield can be loaded with bullets up to 220 grains, but for a .308 caliber to equal the flat trajectory and penetration of a .284 diameter 180-grain bullet with a muzzle velocity of 2,860 ft/sec (870 m/s), as offered for the 7mm Remington Magnum ...
The cartridge is capable of propelling a 117 grain (7.6 g) bullet at up to 3,200 feet per second (980 m/s) and energy levels up to 2,500 ft⋅lbf (3,400 J). Bullets lighter than 75 grains are available in .257 caliber but were designed for the smaller .25-20 Winchester and .25-35 Winchester cartridges and are too lightly constructed for the ...
A reduced-power load of 55 grains (3.6 g) of powder (Carbine Load) was manufactured for carbine use with a muzzle velocity of 1,150 feet per second (350 m/s). [4] In 1884, the US Ordnance Department increased the bullet weight of the 45–70 to 45–70–500, or a 45 caliber bullet, 70 grains of black powder, and a 500 grain bullet. [3]
Typical factory-loaded .22-250 Remington can propel a 55 grain (3.56 g) spitzer bullet at 3,680 ft/s (1122 m/s) with 1,654 ft⋅lbf (2,243 J) of energy. [8] Many other loads with lighter bullets are used to achieve velocities of over 4,000 ft/s (1,219 m/s), while still having effective energy for use in hunting small game and medium-sized ...
The original .357 Magnum load was a 158 gr (10.2 g) bullet with an advertised muzzle velocity of 1,525 ft/s (465 m/s) and muzzle energy of 816 ft⋅lbf (1,106 J). (Muzzle velocity was taken using a large frame revolver with a fairly long barrel of 8.75 in (222 mm)) Most of today's SAAMI conform loads are fairly mild when compared to the ...
Bullets weighing from 100 to 197 [3] grains are available. Bullets in the 120 to 160-grain range will suit most hunting applications while long-range shooters will opt for the heavier bullets to take advantage of their higher ballistic coefficients. [4] Medium burning rifle powders usually work best in the 7mm-08. [citation needed]
