.221 Remington Fireball (P.O. Ackley Data)

Warning! Notes: Standard twist: 14". The .221 Fireball is simply a shortened up .222 Remington, designed for the XP-100 Remington pistol. Chronograph tests have shown that a 22" rifle barrel, chambered for the .221 Fireball will give about 300 feet a second more than the velocity given for the pistol with a barrel slightly under 11" in length.
