Development
The .500/465 Nitro Express is one of several rounds (including the .470 Nitro Express, .475 Nitro Express, .475 No. 2 Nitro Express and .476 Nitro Express) developed as a replacement for the .500/450 Nitro Express following the British authorities' 1907 ban of military caliber ammunition in India and the Sudan, all with comparable performance.[3]
Holland & Holland created the .500/465 Nitro Express by necking down the .500 Nitro Express 3+1⁄4 in.[4]
The .500/465 Nitro Express is designed for use in single-shot and double rifles.
