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." [http://www.chuckhawks.com/5mm_rem_mag.htm The 5mm Remington Rimfire Magnum] " by Chuck Hawks] About 52,000 rifles were sold during its brief production run."

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." [http://www.chuckhawks.com/magnum_rimfire_comparison.htm Magnum Rimfire Comparison: .17 HMR, 5mm Rem. RF Mag, and .22 WMR] " by Chuck Hawks] It uses a 5mm (.20 caliber) bullet that measure convert|0.2045|in|mm, the same as the more recent .204 Ruger cartridge.

For a brief time, Thompson Center Arms offered firearms in 5 mm Mag. 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.

At the 2008 SHOT show, Taurus International introduced the first handgun chambered for the 5mm Remington Magnum rimfire. [ [http://www.gunsholstersandgear.com/2008/02/13/taurus-introduces-a-new-revolver-in-5mm-remington-magnum-rimfire/ Taurus Introduces New Revolver in 5mm Remington Magnum Rimfire] ] Concurrent with the announcement from Taurus, Aguila Ammunition announced they would begin producing 5mm RMR ammunition in 2008.

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. They offered decent performance on small-game and for varmint hunting.
