Here we have my Rigby .350 Magnum Nitro.
The .350 Rigby Magnum was introduced in 1908 as the successor to the popular 400/350 Nitro Express. Rigby developed this rimless caliber for use in the Mauser magnum length action. No other maker, at that time, offered this combination in a magnum-length bolt action rifle and Rigby’s name became synonymous for the best in Mauser-actioned big game rifles.
The .350 can propel a .358 dia., 225 grain bullet at 2,625 fps with 3,440 ft.-lbs. of energy. Big game hunters began using this caliber on elephant, rhino and buffalo, although it was never advertised or recommended for such heavy game. Rigby’s .350 Magnum became the most widely used medium bore caliber throughout Africa and is still used today on Safari.
