The .30 caliber (7.62 mm) armor-piercing bullet on the right has a copper jacket enclosing a hardened penetrator, but externally resembles the other four lead-core bullets. Armor-piercing bullets for rifle and handgun cartridges are designed to penetrate ballistic armor and protective shields intended to stop or deflect conventional bullets.
Compared to standard intermediate cartridges, one can carry more 4.6×30mm ammunition due to the cartridge's lower weight and relatively small dimensions. Also, due to the lower weight of the bullet, aiming in rapid fire is much easier as recoil depends much on the weight of the bullet.
The name .30 Nosler refers to the first two digits in the caliber (0.308 in; 7.62 mm) of the bullets that the cartridge fires and the name of the company which created it. This is Nosler's third cartridge following its predecessors the .26 Nosler which was released in 2014 and the .28 Nosler which was released in 2015.
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 ]
Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
The .30 carbine's relatively straight case and round nose bullet have misled some to believe it was designed for use in pistols.) The .30 carbine uses a lighter bullet (110 grain versus 165 grain) and improved powder. As a result, it has approximately 41% higher muzzle velocity with 27% more impact energy than the parent .32 WSL cartridge.
The 7.62×39mm (also called 7.62 Soviet, formerly .30 Russian Short) [5] round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the global proliferation of the AK-47 rifle and related Kalashnikov-pattern rifles, the SKS semi-automatic rifle, and the RPD/RPK light machine guns.
The .30 TC (0.308 in (7.8 mm) x 1.920 in (48.8 mm) is a non-magnum that is somewhat shorter and wider than the .308 and .30-06. [1] The .30 TC has speed and energy equal to the .30-06. [7] All three cartridges weigh approximately the same, but the .30 TC produces less recoil. The case length of the .30 TC is 1.92 inches.
