The .333 Jeffery Flanged or .333 Flanged Nitro Express is a .333 caliber rimmed, bottlenecked rifle cartridge.[1] It was developed by the W.J. Jeffery & Co. in 1908 as a rimmed version of the .333 Jeffery and is intended for double rifles.[2]

General Information

The .333 Jeffery Flanged was designed for hunting medium game in India and Africa where it was quite popular. It has been used successfully against elephants due to the excellent sectional density of the 300-grain (19 g) bullet, but is considered inadequate for dangerous game.[3] The performance of the .333 Jeffery Flanged mirrors that of the modern .338-06.

John "Pondoro" Taylor treated the cartridge favorably in his book African Rifles and Cartridges.[4]

The .333 Jeffery Flanged was originally loaded with cordite. It is loaded to slightly lower velocities than its rimless counterpart, the .333 Jeffery. Kynoch currently loads ammunition for this cartridge. The .318 Westley Richards was a close contemporary of the .333 Jeffery Flanged.

Bertramm Brass of Australia and Kynoch (by Kynamco) manufacture virgin brass. Factory ammunition is provided by Kynoch.[5]
