.17 Hornady Magnum Rimfire



The .17 Hornady Magnum Rimfire (more comonly known as the .17HMR or, usually jokingly, the .17 Hummer) is a rimfire cartridge introduced by Hornady in 2002. It was designed by a necking a .22 Magnum case to accept a .172 caliber bullet. This gave the .17HMR increased speed over any other rimfire at the time, and gave it an exceptionally flat trajectory, which was ultimately the goal.
