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, with a maximum range of 3,500 yards.

Furthermore, the projectile's high ballistic coefficient allows the .338 Marlin Express to maintain velocity to greater distances than big bore lever cartridges such as .45-70, .444 Marlin, or even the high performance .450 Marlin. Although the heavy bullet weight of these cartridges allow them more muzzle energy, the ballistic advantage of the ...
The .308 Marlin Express is a cartridge developed in 2007 by Marlin Firearms and Hornady. It is based on the .307 Winchester with a goal to duplicate .308 Winchester performance. The cartridge uses a slightly shorter, semi-rimmed case similar to that of the .220 Swift to function in lever-action rifles.
In 1980, two rimmed cartridges based on the .308 Winchester were introduced for use in the Winchester Model 94 XTR angle eject rifle: the .307 Winchester and the .356 Winchester. In 2014, the rimless 45 Raptor was introduced to provide a big bore cartridge for the AR-10 by combining the .308 Winchester with the .460 S&W Magnum. [citation needed]
The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms.It was designed to fill the gap left when the older .45-70 cartridge was not available in new lever-action rifles; at the time it was the largest lever-action cartridge available. [1]
According to the US Army Ordnance Department tests, the 45-70-405 was loaded to 19,000 psi, [4] while the 45-70-500 was loaded to 25,000 psi [2] The average accuracy of the Springfield Model 1873 was a circle with an average radius of 1.7 inches at 100 yards, corresponding to an ~3.4 MOA.
Muzzle energy is dependent upon the factors previously listed, and velocity is highly variable depending upon the length of the barrel a projectile is fired from. [2] 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.
The .577/450 Martini–Henry is a black powder, centrefire rifle cartridge.It was the standard British service cartridge from the early 1870s that went through two changes from the original brass foil wrapped case (with 14 parts) to the drawn brass of two parts, the case and the primer.
