A friend just picked his new Savage up last week. After handling it for a few minutes I was not impressed at all. Very cheap looking and feeling IMO. If that's the only gun chambered in this new round I won't be trying one.
Just for reference volquartsen announced a semi .17wsm, Franklin armory is/has released an AR platform in the .17wsm, and I know of a couple people who have converted single shot break open guns from .17 hmr to .17wsm
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.
