The heavier bullet produced significantly superior ballistics and could reach ranges of 3,350 yd (3,060 m), which were beyond the maximum range of the .45-70-405. While the effective range of the .45-70 on individual targets was limited to about 1,000 yd (910 m) with either load, the heavier bullet produced lethal injuries at 3,500 yards (3,200 m).
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, [3] to more than 1,200 m/s (3,900 ft/s) [4] in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to 1,700 m/s (5,600 ft/s) [5] for tank guns firing kinetic energy penetrator ammunition.
To equal the .444 Marlin bolt thrust, you'd have to load the .45-70 to 35,000 PSI, significantly over the SAAMI limit of 28,000 PSI. There are available commercial T/C loads for the .45-70 that exceed 2500 ft. lbs., which meets the .500 S&W energies available with an equivalent sectional density.
The .45-75 was shorter and fatter than the .45-70 government cartridge. Although the .45-75 was nominally superior to the popular .45-70, the weak toggle-link action with its elevator-style carrier originally designed for handgun cartridges limited the ability of the Model 1876 rifle to safely fire higher pressure loads intended for stronger ...
The Rolling Block was also one of two makers rifles used by the American team to win the International Long Range matches held at Creedmoor Rifle Range on Long Island, New York, in 1874. Team members shot against the Irish team with half the shooters using Rolling Block Creedmoor models, and the other half using Sharps Model 1874 Long Range rifles.

The tyre load index (LI) on a passenger-car tire is a two- or three-digit numerical code used to cross-reference a load & inflation table that will give the maximum load each tire can carry at a given pressure. The load index is sometimes used in conjunction with the load range, which appears elsewhere on the tire.
