The rimmed.30-40 round was also known as .30 Army or .30 U.S. Although the .30-40 Krag was the first smokeless powder round adopted by the U.S. military, it retained the "caliber-charge" naming system of earlier black powder cartridges, i.e. a .30-caliber bullet propelled by 40 grains (2.6 g) of smokeless powder.
However, it has been said that in a modern rifle it can be loaded to equal the .30-30 Winchester up to 300 yards (270 m). [3] In 2020, a Model 1894 Winchester rifle made in 1912 chambered in .32-40 Winchester was used by David J. LaPell in the Adirondack Mountains of New York to shoot a whitetail buck at the distance of approximately 60 yards.
The .30-378 Weatherby Magnum is a .30 caliber, belted, bottle-necked rifle cartridge. [2] The cartridge was developed in response to a US Army military contract in 1959. While still unreleased to the public, the cartridge went on to set world records for accuracy including the first ten 10X in 1,000 yards (910 m) benchrest shooting. [ 3 ]
40 mm high-velocity high-explosive dual-purpose M430A1 cartridge 40×53 mm high-velocity ammunition belt. 40×53 mm HV (high velocity) [2] is a NATO-standard [3] high–low grenade launcher cartridge meant for mounted or crew-served automatic grenade launchers, such as the Mk.19 AGL, Mk 47 Striker, HK GMG, STK 40 AGL, and Daewoo K4.
It is a suitable round for engaging helicopters, aircraft and lightly armored vehicles, as well as unarmored vehicles, and it is capable of igniting jet fuel. The Mk 211 has about the same destructive power as a standard 20mm round against such targets and can penetrate 11 mm of RHA at 45° from a range of 1000 meters. [4]
The .300 AAC Blackout (designated as the 300 BLK by the SAAMI [1] and 300 AAC Blackout by the C.I.P. [2]), also known as 7.62×35 mm, is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine.
