The 350 Remington Magnum and its companion, the 6.5mm Remington Magnum, were probably the first of the short, fat magnums, introduced in 1965. They are based on the belted 300 H&H case shortened to 2.170 inches so as to fit into short bolt-actions. The 350 Remington was introduced in the short and extremely light Remington Model 600 carbine. It quickly got a reputation for ferocious recoil, which it surely has in a very light rifle. Despite numerous efforts to revive it in heavier platforms the 350 Remington Magnum has never become popular. However, it has a small but extremely loyal following among big woods hunters who want their bucks, bears, and boars anchored on the spot. This it does, but it is also fairly flat-shooting and versatile, very similar in performance to the 35 Whelen--but in a shorter action. Remington's remaining factory load features a 200-grain bullet at a respectable 2775 feet per second. —
