About the Cartridge

This cartridge is based on a .22 caliber LR rimfire case that is necked down to seat a 17 grain, .17 caliber Hornady V-Max bullet. Although the overall length of the .17 Mach 2 is the same as the .22 LR, the necked portion of the casing is extended to support the smaller projectile. Keeping the overall size the same as the .22 LR made it easier for manufacturers to re-tool .22 caliber rimfire guns to the new .17 Mach 2 cartridge. This is a lightweight supersonic varmint round that, as its name indicates, travels almost twice the speed of sound. Its speed and weight provide a near-flat trajectory to 100 yards, but past that distance it looses effective energy.
