.17 Remington Fireball

.17 Remington Fireball

Description

The .17 Remington Fireball was created in 2007 by Remington Arms Company as a response to the popular wildcat round, the .17 Mach IV. Factory loads drive a 20 grain bullet around 4,000 ft/s. Velocity is close to the .17 Remington but with significantly less powder, and therefore less heat and fouling.Wikipedia
