Most VLD bullets are used in rifles. VLD bullets typically have a ballistic coefficient greater than 0.5, although the threshold is undefined. [1] Bullets with a lower drag coefficient decelerate less rapidly. A low drag coefficient flattens the projectile's trajectory and also markedly decreases the lateral drift caused by crosswinds. The ...
In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
Calculating the trajectory from the previous sentence indicates a ballistic coefficient (G1 BC) of approximately 0.34. After that, military ball ammunition loaded with an 11.25 g (173.6 gr) spitzer bullet fired at a muzzle velocity of 725 m/s (2,379 ft/s) with 2,957 J (2,181 ft⋅lbf) muzzle energy from a 589 mm (23.2 in) long barrel became ...
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. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
Battle rifles are full-length, semi-automatic or select fire rifles that are chambered for a full-power rifle cartridge, [1] and have been adopted by a nation's military. The difference between a battle rifle and a designated marksman rifle is often only one of terminology with modifications to the trigger and accuracy enhancements; many of the weapons below are currently still in use and have ...
The .276 Enfield was designed with the intent of being more powerful than the .303 British cartridge used in the Lee–Enfield rifles and to be at least similar in size and performance to other large, powerful early 20th century military rifle cartridges, like the .280 Ross, 7.92×57mm Mauser, .30-06 Springfield and 7.5×55mm Swiss GP11.
Designated marksman rifles have to be effective, in terms of hit rates and terminal ballistics, at application ranges exceeding those of ordinary assault rifles and battle rifles, but do not require the extended-range performance of a dedicated sniper rifle. For this, depending on the military, sometimes specialized 7.62×51mm NATO ammunition ...
The M110A2 is an improved version of the original M110 rifle with M-LOK rails, an improved gas system, new suppressor, and adjustable stock. [2] This fills the gap of semi-automatic sniper rifles as most all of the M110A1 rifles issued were the SDMR variant and not designed for sniper work. [16]
