Overview

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 .375 in (9.5 mm) caliber.

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 270 gr (17 g) projectile at 2,525 ft/s (770 m/s).

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".
