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 unrelated Henry Repeating Arms produces a modernized replica of the Henry Model 1860 rifle with brass receiver and American walnut stock, but a modern steel barrel and internal components. [ 14 ] Uberti produces an almost exact copy Henry Model 1860 chambered in .44-40 Winchester or .45 Colt, rather than the original .44 Henry rimfire.

In 1990, the Western film Quigley Down Under, Tom Selleck's title character uses a Sharps rifle chambered in the .45-110, also known as the 45-2 7 ⁄ 8" Sharps. Theater Crafts Industry went so far as to say, "In Quigley Down Under , which we did in 1990, the Sharps rifle practically co-stars with Tom Selleck."
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.
The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. In 2009 an additional three calibers were tested and in 2010 and 2011 more calibers were added. Also in 2011 testing was carried out to study the "cylinder gap effect" on the velocity of ammunition shot from ...
The ballistic performance of a .577/450 is somewhat similar to that of an American .45/70 Government round, as used prolifically throughout the American Frontier West and by buffalo hunters, though the .577/450 has more power due to its extra 15 grains of black powder inside the cartridge case.
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] The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle.
