In 1884, the US Ordnance Department increased the bullet weight of the 45–70 to 45–70–500, or a 45 caliber bullet, 70 grains of black powder, and a 500 grain bullet. [3] The new 45-70-500 loading was recorded with a muzzle velocity of 1315.7 feet, and generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards ...
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 test results were obtained from many shots, not just a single shot. The bullet was assigned 1.062 lb/in 2 (746.7 kg/m 2) for its BC number by the bullet's manufacturer, Lost River Ballistic Technologies, before it went out of business. Measurements on other bullets can give totally different results.
Measuring the ballistic performance of armor is based on determining the kinetic energy of a bullet at impact (E k = 1 ⁄ 2 mv 2). Because the energy of a bullet is a key factor in its penetrating capacity, velocity is used as the primary independent variable in ballistic testing.
Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well. There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 ...
The muzzle velocity of the carbine bullet was 1,150 feet per second. The 1884 model rifle generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards, with a maximum range of 3,500 yards.

The .450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, [4] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun.
