The .369 Nitro Express, also known as the .369 Purdey Nitro Express, is a centerfire, rifle cartridge developed by James Purdey & Sons and introduced in 1922.
The .369 Nitro Express is a rimmed cartridge originally designed for use in Purdey's own double rifles. The cartridge offers almost identical ballistic performance to the .375 H&H Flanged Magnum, firing a projectile of the same 0.375inches caliber.[2]
As is common with cartridges for double rifles, due to the need to regulate the two barrels to the same point of aim, the .369 Nitro Express was offered in one loading, firing a 270gr projectile at 2525ft/s.[1]
In his African Rifles and Cartridges, John "Pondoro" Taylor said of the .369 Nitro Express that you "would need to go a very long way to get a better general purpose weapon".[3]
