History
Developed in the early 1880s as the 'express' load for the Sharps Model 1874, it was used primarily for very long range target shooting competitions. With 140 grains of black powder and 700-grain bullets, it was capable of 1,500-yard accuracy in skilled hands. Buffalo hunting had largely ended by the time the cartridge appeared, so its use was mostly target-oriented. Pedersoli and other reproduction makers still offer rifles chambered for it; brass is available from Starline.
