Introduced to the market around 1898, the 577 Nitro Express was a smokeless upgrade to the 577 Black Powder Express capable of delivering a 750 grain bullet with a muzzle velocity of over 2000 feet per second. The combination of the 577 NE with a stout and reliable English double rifle gave hunters a weapon that could be counted on to bring down dangerous game with lower powered rounds becoming popular with Indian tiger hunters and the full-load 3 inch cartridge adopted by African elephant hunters both as a primary weapon and a close-range emergency gun for dealing with charging elephants. Fitted with a ramp bead front sight with a sliding hood and a drift adjustable "U" notch rear sight marked "50". With a platinum accent wire and a pair of claw bases on the checkered quarter rib, light engraving at the breech, "HOLLAND & HOLLAND." on the right barrel, "98. NEW BOND STREET, LONDON." on the left, "MADE IN ENGLAND" on the underside of the rib and a series of London Proof House stamps on the water table, including a 3 inch chamber marking, Nitro proofs, and "1000-750 MAX".
