A popular 7 mm hunting caliber bullet is actually .283 in diameter (7.2 mm), but wildcat cartridges using this caliber bullet in a 5.56 x 45 case have so far not been successful. There is an existing and well-developed use of hunting-rifle bullets in the .277 caliber (6.8 mm), introduced by Winchester as the 270 in 1925.
If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr
The .458 SOCOM (11.63×40mmRB) is a moderately large round designed to work in an AR-15 platform.This is achieved by installing a 458 bolt and barrel. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), [1] similar to a light .45-70 but with a much smaller case.
RCBS reloading dies are also currently available for the cartridge. When firing a 9.7 g (150 gr) AccuBond Long Range bullet from a rifle with a 660 mm (26 in) barrel, the .27 Nosler has an approximately 120 m/s (400 ft/s) advantage over the .270 Winchester , about a 90 m/s (300 ft/s) advantage over the .270 WSM , and about a 30–46 m/s (100 ...
In hunting applications, the 7.62×40mm WT delivers slightly more energy than the 7.62×39mm and is similar to the 6.8 SPC [7] and .30-30 Winchester, making it useful for game such as deer and feral hogs, particularly for hunters who want to use an AR-15, but cannot legally use the 5.56 round, due to its low power factor on game.
This is a list of firearm cartridges which have bullets in the 5.00 to 5.99 mm (0.197 to 0.236 in) caliber range. Length refers to the cartridge case length. OAL refers to the overall length of the cartridge. All measurements are in mm (in).
It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round.
The 5.6×39mm, also known in the U.S. as .220 Russian, is a cartridge developed in 1961 for deer hunting in the USSR. [3] It fires a 5.6mm projectile from necked down 7.62×39mm brass. While it originally re-used 7.62x39 cases, once it became popular enough commercial ammunition started being manufactured, both in the USSR and in Finland.
