The imperial unit kilograin foot per second (kgr⋅ft/s). "Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo ...
When the .470 Capstick is loaded with a 500-grain (32 g) bullet to a muzzle velocity of 2,300 ft/s (700 m/s) and sighted in 3 inches (76 mm) high at 100 yards (91 m), it is only about a foot low at 300 yards (270 m), giving it more effective range than many cartridges which are popular for deer and elk hunting.
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
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 ...
The DBP10 cartridge was developed in 2010 and has a hardened steel-cored 4.6 grams (71 gr) bullet, a muzzle velocity of 915 metres per second (3,002 ft/s) from a standard barrel (Type 95 / QBZ-95, 463 mm barrel length) and was designed to match nine different then serving 5.8×42mm chambered weapons. These weapons featured different barrel ...
Example: A .44 Remington Magnum with a 240-grain (0.016 kg) jacketed bullet is fired at 1,180 feet per second (360 m/s) [2] at a 170-pound (77 kg) target. What velocity is imparted to the target (assume the bullet remains embedded in the target and thus practically loses all its velocity)?

The .450 Dakota launches a 500 gr (32 g) at 2,550 ft/s (780 m/s), a 550 gr (36 g) at 2,450 ft/s (750 m/s) and a 600 gr (39 g) at 2,350 ft/s (720 m/s). The .450 Dakota should be considered the ballistic equivalent of the .460 Weatherby Magnum from the standpoint of power and operating pressure. .450 Rigby performance tends to be somewhat lower ...
