History

In the early 1960s Remington was working on an experimental bolt-action pistol based on their model 600 action. The goal was a highly accurate pistol that would be well suited for competition. After working with the .222 Remington they determined that it contained more powder capacity than was necessary to work efficiently in the shorter barrels of pistols. While rifle barrels commonly range in length from , pistol barrels are typically much shorter, ranging from although occasionally up to for some competition barrels. As a result, Remington decided to develop a shorter version of the .222 Remington cartridge, optimized for use in the XP-100. While production of XP-100 pistols chambered in .221 Fireball was eventually canceled after 1985,Remington Arm

pressure. The maximum SAAMI pressure level for the .221 Fireball is 52,000 C.U.P. as compared to 46,000 C.U.P. for the .222 Remington. The purpose of the increased pressure was to allow it to perform more effectively in the shorter barrel of the XP-100. The .221 Fireball produces the highest velocity of any commercial pistol cartridge.

The .221 Fireball has been used by wildcatters to create a small efficient .17 caliber cartridge. The most common is the .17 Mach IV which is essentially the .221 necked down to the smaller caliber. This cartridge is reported to have a very flat trajectory and to be relatively quiet with low recoil. It has been so popular as a wildcat that in 2007 Remington legitimized it by introducing their own version only slightly different from the Mach IV and calling it the .17 Remington Fireball. A .20 caliber version is also gaining popularity called the .20 VarTarg (VT), "vartarg" being the combination of the words "varmint" and "target". The .221 Fireball has also been used as the base for the
