The .17HMR is the same as the rounds made by keen rimfire wildcatters who worked to make a rimfire cartridge with a great flat trajectory. Such wildcatters were looking for matching the ballistics of the obsolete 5 mm Remington Rimfire Magnum that was made from 1970 to 1974, and was up to that extent the fastest rimfire cartridge ever developed. With about 5 mm diameter barrels as well as bullets being almost unavailable at the moment (the 5mm RMR was the final commercial 5 mm round after the 2004 release of the centerfire .204 Ruger), the commercially available .17 caliber turned into their bullet of choice.

The terminal ballistics of the bullets of the lightweight limit the .17 HMR to little game animals as well as varmints. .17 HMR ammo is not so much common but rather costlier than the .22 caliber rimfire rounds, yet this is changing as the fame of Bulk 17 HMR Ammo rifles assembles momentum.
