Designed around the hard-hitting performance of the famous Hornady V-Max bullet, this ammunition is specifically designed for supremely accurate long-range shooting. The polymer tip enhances accuracy and promotes devastating expansion. It also increases the ballistic coefficient and stabilizes the bullet in flight. This ammunition is new production and non-corrosive.This cartridge is based on the 22 Long Rifle necked down to 17 caliber. It is not a variation of the 17 Hornady Magnum Rimfire (HMR) and is not interchangeable with it.
