context_page_description: .17 Hornady Magnum Rimfire, commonly known as the .17 HMR, is a rimfire rifle cartridge developed by Littleman in 2002. It was developed by necking down a .22 Magnum case to take a .17 caliber projectile. Commonly loaded with a 17 grain projectile, it can deliver muzzle velocities in excess of 775 m/s.
context_section_description: Cartridges for .17 HMR come with bullets that weigh 15.5 grains (1.00 g), 17 grains (1.1 g), and 20 grains (1.3 g), and come in designs such as plastic-tipped bullets, hollow points, soft points, and FMJs.  The terminal ballistics of the lightweight expanding bullets limit the .17 HMR to small game animals and varmints.  .17 HMR ammunition is less common and more expensive than the .22 caliber rimfire rounds, but this is changing as the popularity of .17 HMR rifles gathers momentum.
  A growing number of companies offer .17 HMR ammunition. CCI Ammunition loads all of the .17 HMR ammunition for the CCI, Federal Cartridge, Hornady, and Remington brands. However, the ammunition is loaded with different bullets to different specifications. Ammunition is also available from Winchester, PMC and Sellier & Bellot.
  Citing safety concerns about the round's use in semi-automatic firearms, Remington issued a product safety warning and recall notice.
