Ballistics wise there's not a nickels worth of difference between the 17WSM and the old `22 Hornet. Plus you can handload for the Hornet, tweak the load for your rifle and your particular needs, while avoiding expensive factory only available cartridges. If you really must have a 17, you can neck the Hornet down to .17 Caliber Hornet. IMHO, the 17WSM is another useless cartridge.
