Cartridge Profile: .450 Rigby

The .450 Rigby is a modern British dangerous-game cartridge standardized by C.I.P. It uses a large rimless, bottleneck case and is intended for magazine-fed rifles.

The cartridge was developed by John Rigby & Co. during the 1990s as a large-bore companion to the firm's established bolt-action dangerous-game rifles.

It should not be confused with the older rimmed .450 Nitro Express cartridges intended primarily for single-shot and double rifles.

Bertram manufactures these cases in Australia.

Does Desert Tech Munitions import Bertram brass directly?

Desert Tech Munitions is the authorized U.S. Bertram distributor and imports Bertram products for the U.S. market.
