For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
The .50 caliber Mk 257 API-DT has a purple bullet tip. The bullet has a hardened steel core and incendiary tip. It is used in the M2, M3, and M85. Dim tracer reduces the possibility of the weapon being located during night fire and is visible only with night-vision devices. [22] Cartridge, caliber .50, armor-piercing (AP), Mk 263 Mod 2
Winchester improved the .50 caliber round to have similar performance. Ultimately, the muzzle velocity was 2,750 ft/s (840 m/s). [24] Efforts by Browning and Fred T. Moore resulted in the water-cooled, .50 caliber M1921 Browning machine gun and an aircraft version. These guns were used experimentally from 1921 until 1937.
The TAC-50 is a military and law enforcement weapon, which, designated as the C15, has been the standard long-range sniper weapon (LRSW) of the Canadian Army since 2000. Rifles of the TAC-50 family are guaranteed to provide 0.5 minute of angle ( MOA ) groups with match-grade ammunition under ideal conditions.
In summer 2002, the M82 finally emerged from its Army trial phase and was officially adopted as the Long Range Sniper Rifle, Caliber .50, M107. The M107 uses a Leupold 4.5–14×50 Mark 4 scope. [5] The Barrett M107 is a .50 caliber, shoulder-fired, semi-automatic sniper rifle.
The .50 Action Express (AE) (12.7×33mmRB) is a large-caliber handgun cartridge, best known for its usage in the Desert Eagle. Developed in 1988 by American Evan Whildin of Action Arms, the .50 AE is one of the most powerful pistol cartridges in production.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

With normal bullet weights between 300 and 400 grains (19 and 26 g), overall cartridge length shorter than that of an AR-15 magazine well, and holding to pressures of 33,000 psi limited by the AR bolt strength system, [2] the .50 Beowulf is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of ...
