The 5mm Remington Rimfire Magnum is back!

The 5mm Rem Magnum was originally produced from 1970 to 1974. Only a few firearms where chambered in it. The bolt action Remington Model 591 and Model 592 where chambered in it and Thompson Center Arms offered it for a brief period of time.

In comparison the 30 gr .22 Magnum (WMR) traveling at 2,200 ft/s generates 322 ft/lb of energy.
