The polymer tip of a V-Max bullet delivers more than tack driving accuracy at long range it also creates dramatic expansion on impact. The flat trajectory delivered by the 17 HMR makes it the most accurate long range rimfire ever made. The uniformity of the Hornady 17 HMR case is equaled only by ultra-expensive match ammo, and case geometry helps provide this cartridge's unequaled performance. The powerful propellants available today make the 17 HMR the most accurate, hardest hitting rimfire cartridge available.
