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 ...
Firing factory-loaded ammunition with bullets ranging from 90 to 129 grains (5.8 to 8.4 g), its muzzle velocity varies from 2,500 ft/s (760 m/s) with 129- and 130-grain (8.4 g) bullets to 2,900 ft/s (880 m/s) with 90 gr (5.8 g) bullets (similar in velocity to a 77-grain (5.0 g) 5.56 mm round). Depending on their case material and bullet weight ...

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]
Probably the most popular weight for the 300 Win Mag is the 180 grain bullet, with high ballistic coefficient and capable of taking down light skinned big game of any weight. The 180 and 185 grain bullets are also considered the most versatile, with a muzzle velocity of 2950 fps from average factory loads. [12] [13]
Commercially manufactured rifles chambered in .30-06 are popular for hunting. Current .30-06 factory ammunition varies in bullet weight from 7.1 to 14.3 grams (110 to 220 grains) in solid bullets, and as low as 3.6 grams (55 grains) with the use of a sub-caliber bullet in a sabot. [28]
