The .327 Federal Magnum was announced in November 2007 by Federal Cartridge. The .327 Magnum was designed to get .357 Magnum performance from a small revolver, without losing the ability to load six rounds (instead of five). This cartridge lives up to the expectations and does so with less muzzle blast and recoil than any comparable .357 Mag available.
Ruger was the first company to market a revolver for this new cartridge, the SP101. Learn more about the .327 Federal Magnum at Ammo.com.
