5 Mm Remington Rimfire Magnum

The 5 mm Remington Rimfire Magnum is an obsolete bottlenecked rimfire cartridge introduced by Remington Arms Company in 1970. Remington chambered it in a pair of bolt-action rifles, the Model 591 and Model 592, but the round never became very popular, and the rifles were discontinued in 1974. The ammo was discontinued in 1982. About 52,000 rifles were sold during its brief production run. As of 2008, Aguila, a Mexican ammunition company, is producing 5mm Remington Magnum ammunition.
