The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
For comparison, Hornady's 9249 load for the .500 S&W Magnum cartridge offers slightly less energy at the muzzle, achieving 2,868 ft⋅lbf (3,888 J) by driving a 300 grain (19 g) FTX bullet at 2,075 ft/s (632 m/s). Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by ...
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 ...

The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 pounds (1,300 kilograms) automobile traveling at 20 miles per hour (32 kilometres per hour). In a 110 lb (50 kg) rifle, this will develop well over 200 foot-pounds force (270 joules) of free recoil energy. Shooting usually involves a heavy "lead sled" or similar ...
Conversion from kilo grain feet per second to newton-seconds is trivial, since both the grain and foot is based on SI units. One troy grain is defined as 0.064 798 91 grams exactly [ 1 ] and one international foot is defined as 0.3048 meters , giving the exact conversion factor of 0.019 750 707 768 .
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
The AT4 may be considered a disposable, low-cost alternative to a Carl Gustaf 8.4 cm recoilless rifle. The AT4 took many of its design features from the Carl Gustaf, which operates on the principle of a recoilless weapon , where the forward inertia of the projectile is balanced by the inertia of propellant gases ejecting from the rear of the ...
