What is 45-90?

45-90 is a rifle cartridge primarily used for long-range shooting and hunting. It is a rimless bottlenecked rifle cartridge developed by Sharps Rifle Company in the late 1800s. The cartridge is known for its high velocity and flat trajectory, making it popular among long-range shooters.

The 45-90 cartridge is loaded with a .458 caliber bullet and typically has a muzzle velocity of around 1,400 to 1,800 feet per second, depending on the specific load and barrel length. It has a maximum effective range of around 1,000 yards, making it suitable for hunting medium to large game at long distances.

45-90 ammunition is not as common as some other rifle cartridges, but it is still produced by some manufacturers and can be found at specialty shops and online retailers. Reloaders can also make their own 45-90 ammunition using brass, primers, powder, and bullets designed for this caliber.
