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 unfortunately the round never became very popular, and the rifles were discontinued in 1974. The ammo discontinued in 1982.[2] About 52,000 rifles were sold during its brief production run.[3] As of 2008, Aguila, a Mexican ammunition company, is producing 5mm Remington Magnum ammunition.[4]

[edit] Design
Remington designed a new case that was very similar to the older .22 Mag, but stronger to handle the higher pressure of the 5 mm at 33,000 PSI.[5] It uses a 5mm (.20 caliber) bullet that measure 0.2045 inches (5.19 mm), the same as the more recent .204 Ruger cartridge.
For a brief time, Thompson Center Arms offered firearms in 5 mm Mag.[3] From 1982 until 2008, no ammunition manufacturers manufactured rounds for this cartridge, but some firearms manufacturers are creating conversion kits to allow the existing 5 mm guns to shoot other more-common cartridges.[3]
At the 2008 SHOT show, Taurus International introduced the first handgun chambered for the 5mm Remington Magnum rimfire.[6] Concurrent with the announcement from Taurus, Aguila Ammunition announced they would begin producing 5mm RMR ammunition in 2008.
[edit] Performance
The 5 mm Mag offered higher velocity than the .22 WMR and more energy than either the .22 WMR or the later .17 HMR.[2] They offered decent performance on small-game and for varmint hunting.[1]
