The .204 Ruger is a centerfire rifle cartridge developed by Hornady and Ruger. At the time of its introduction in 2004, the .204 Ruger was the highest velocity commercially produced ammunition, and the only cartridge produced commercially for bullets of .204 inch/5 mm caliber.
These .204 Ruger cartridges are designed for efficient elimination of groundhogs, coyotes, and other "varmint" animals. Manufactured by Winchester at its newest production facility in Oxford, Mississippi, these cartridges fire a very light 32 grain polymer-tipped bullet at an astounding muzzle velocity of 4,000 feet per second. This combination produces instant fragmentation that's sure to bring your target down quickly without risking overpenetration.
