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 ...

The 45-70-500 Government is an example. Often, the name reflects the company or individual who standardized it, such as the .30 Newton , or some characteristic important to that person. The .38 Special actually has a nominal bullet diameter of 0.3570 inches (9.07 mm) (jacketed) or 0.3580 inches (9.09 mm) (lead) while the case has a nominal ...
The .460 S&W, which is a .45 caliber case slight longer than the .500 S&W, takes nearly the same bullets as the .45-70 (.452 vs. .458), and is a virtual twin to the .45-70 performance-wise. Even the guy at S&W who developed the .500 and .460 thinks the .460 is a better hunting cartridge (see here ).
The 6mm Lee Navy (6×60mmSR), also known as the 6mm U.S.N. [1] or .236 Navy, [2] is an obsolete American rifle cartridge. [3] It was the service cartridge of the United States Navy and Marine Corps from 1895 (therefore replacing the .45-70 Government rifle cartridge) to 1899, when it was then itself replaced by the more modern .30-40 Krag rifle cartridge.
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.
These factors, along with Taylor’s dismissal of muzzle energy, allow many obsolete low powered large bore cartridges such as the .577/450 Martini-Henry and the .45-70 Government to have as much as twice the TKOF than the smaller bore general purpose hunting cartridges such as the .303 British and the .30-06 Springfield. For these reasons the ...
With these bullets the Lott can be loaded to the power level of the original .45-70 Government cartridge. which was a 405 gr (26.2 g) bullet at 1,330 ft/s (410 m/s). What the .458 Lott lacks in velocity and energy compared to the .450 Rigby or the .460 Weatherby Magnum, it more than makes up for by virtue of its versatility.
