The .303 Magnum is a bottleneck centerfire rifle cartridge developed by W.J. Jeffery & Co and introduced in 1919. It was produced in both semi-rimmed and rimless versions.[2]
Overview[]
The cartridge was designed by Jeffery for target shooting, and was used for some time by the British Match Rifle Committee.[2] The .303 Magnum's case capacity is the same as the .30-06 Springfield, although performance was considered to favour the .303 Magnum. The .303 Magnum had a brief life, only appearing in the Kynoch catalogue until 1930.[1]
The .303 Magnum fires a 174 gr projectile at 2850 fps.
