Calibers available to the rimfire shooter are (left to right) the 17 Aguila, 17 Mach 2, 17 HMR, 22LR, and 22 WMR. Although all are useful, each has its advantages and disadvantages.

Introduced in 2004, the 17 Mach 2 is gaining wide acceptance. Note the mention on the label of the “first production run” on this box.

Two cartridges that the author (and many others) would like to see brought back are the 5mm Remington (left) and the 25 Stevens (right).

17 Mach 2

The 17 HMR represents a 22 WMR case necked to hold 17-caliber bullets, but consider the potential of a 22 LR case necked to hold a 17-caliber bullet. An enormous number of rimfire rifles could become 17-caliber rifles simply by changing the barrels. In order to produce a cartridge that would hold enough powder to give a high velocity, the case used could be that of the CCI Stinger which is 0.700 inch long rather than 0.600 inch of the normal 22 LR. These procedures are exactly those used by Hornady and CCI to produce the 17 Mach 2, which launches a 17-grain bullet at 2,100 ft/sec (which is approximately twice the velocity of sound hence the name Mach 2).
