The .204 Ruger is a centerfire rifle cartridge that was introduced in 2004 as a joint development between Ruger, an American firearm manufacturer, and Hornady, a prominent ammunition company. This cartridge was specifically designed for varmint hunting, targeting small game and predators like coyotes, foxes, and prairie dogs.
The .204 Ruger is based on the .222 Remington Magnum case, necked down to accommodate a smaller .20 caliber (5mm) bullet. It is known for its flat trajectory, high velocity, and low recoil, making it an excellent choice for long-range shooting of small, fast-moving targets. Typical bullet weights for the .204 Ruger cartridge range from 24 to 40 grains, with muzzle velocities up to 4,225 feet per second, depending on the load.
The .204 Ruger quickly gained popularity among varmint hunters due to its performance and has become one of the most popular cartridges in its category. It offers a good balance of speed, accuracy, and low recoil, while also producing less wind drift than other similar caliber cartridges, making it an excellent choice for long-range shooting in windy conditions.
