Description:

This cartridge is based on a .22 Magnum (WMR) rimfire case that is necked down to seat a 17 grain, .17 caliber Hornady V-Max bullet. As done with the .17 Mach 2, the .17 HMR is sized such that manufacturers can easily re-tool .22 WMR gun designs to the new .17 HMR cartridge. This is a supersonic varmint round that travels over twice the speed of sound with near flat trajectory to 100 yards. The larger cartridge and load gives the .17 HMR more than 1-1/2 times the energy at 100 yards than the smaller .17 Mach 2.
