Because the .17 calibers have become so popular I thought it would be a good idea to note the difference between the two different .17 Calibers.
One is the .17 HMR (Hornady Magnum Rimfire)
The other is the .17Mach2 sometimes called a .17M2..
You can see by cartridge comparison the relationship to the .22 Calibers
The Bottom line is simple, the .17M2 and the .22LR were designed for small game out to 100 yards.
While the .17HMR (Hornady Magnum Rimfire) and the .22WMR (Winchester Magnum Rimfire)
were designed for small to med. game at longer ranges.
