Factory loads drive a 20 grain (1.3 g) bullet around 4,000 ft/s (1,219 m/s). Velocity is close to the.17 Remington but with significantly less powder, and therefore less heat and fouling. Both are important issues to high-volume shooters such as varmint hunters.

It is based on the.221 Remington Fireball necked down to accept a.17 caliber bullet and is very similar to the.17 Mach IV. Reports on this cartridge show mild recoil, high velocity, with minimal report (noise).
