History

It began as a black powder round, and then became a smokeless round. It fires a 750 grain bullet (about 48.6 grams) at a muzzle velocity of around 2050 feet per second (625 m/s), depending on the type and amount of powder used. Rifles chambered in .577 Nitro Express are still in production, and are made by companies including Heym, Holland & Holland, and James Purdey.
