Ashley Hlebinsky, the Robert W. Woodruff Curator at the Cody Firearms Museum, highlights George Armstrong Custer's Sharps Rifle. Sharps rifles are a series of large-bore single-shot rifles, beginning with a design by Christian Sharps in 1848, and ceasing production in 1881. They were renowned for long-range accuracy. By 1874 the rifle was available in a variety of calibers, and had been adopted by the armies of a number of nations.
