MV: Muzzle velocity, in feet-per-second; ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] 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 ...
Muzzle device: Most DMRs utilize the traditional M14 muzzle device, although since deployment in 2001, some DMRs are now equipped with the OPS, Inc. 2-port muzzle brake, which is threaded and collared to accept an OPS-Inc. 12th Model sound suppressor.

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 propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [2] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant.
