Overview

The .246 Purdey is a rimmed cartridge originally designed for use in Purdey's own double rifles. Never popular or widely used, the cartridge offers slightly less power than the .243 Winchester.

As is common with cartridges designed for double rifles, the .246 Purdey was offered in one loading, firing a 100 gr projectile at 2950 fps.
