Ed. note: For the latest on the Taurus 590 revolver in 5mm, scroll to the bottom of this post.
With a recent surge of interest in rimfire cartridges not starting with the number 22, Taurus International announced a new revolver in their Tracker line chambered for the 5mm Remington Rimfire Magnum (RFM) cartridge.
For those not familiar with the 5mm RFM, the rimfire cartridge was introduced in 1970 by Remington Arms Co. Along with the cartridge, Remington introduced two rifles chambered for the 5mm, the models 591 and 592. However, a lack of sales and concerns about pressures prompted Remington to cease sales of the rifles in 1974, and by the early 1980’s, they stopped making the ammunition as well. However, like many discontinued cartridges, the 5mm rimfire has a small, loyal band of followers who have kept interest in this cartridge alive.
