The .350 Rigby Magnum is vastly overlooked even among rifle cranks but was at one time as popular as the .375 H&H Magnum. Released in 1908, it is an entirely original design, and was the first to feature the sharp 45-degree shoulder which is the hallmark of the Rigby designs.
Each shooter’s recoil tolerance level is different, and some people appreciate flexibility over specific application, but these five cartridges will cleanly take any dangerous-game animal on earth.
