The model 1884 was also produced in a carbine version. It was found that the rear sight could be easily damaged when removing the rifle from the carbine boot. The rear barrel band was therefore modified in 1890 to include a rear sight protector. A round-rod bayonet model was also produced, designated the Model 1888.
The .45-70 (11.6x53mmR), also known as the .45-70 Government, .45-70 Springfield, and .45-2 1 ⁄ 10" Sharps, is a .45 caliber rifle cartridge originally holding 70 grains of black powder that was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873.
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 length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
The largest factory caliber offered for the Contender was the .45-70, which, although a much larger case than the .308, is still feasible because of the relatively low cartridge pressures of the original black-powder round relative to the limits of the bolt face of the Contender receiver.
The Ruger #3 is a single-shot rifle produced by Sturm, Ruger & Co from 1973 to 1986. It is based on the Ruger #1, with some modifications made to reduce costs, such as a simpler one-piece breech lever. [3]

The limitations on bolt travel of a converted Model 336 rifles are generally limit its case overall length (COL) to 2.85 inches. The 2.85 COL allows all bullets that work with the .45-70 action to be used in the converted .45-90. The .45-90 converted 1895 actions have the same pressure limitations as the .45-70 actions.
