The .17WSM (not to be confused with 17HMR) is a much more powerful cartridge than the 22WMR. The WSM is a necked down 25cal power-fastener case, longer and larger diameter than the 22WMR, yielding about 50% more muzzle energy than the 22WMR.
I'd be interested to see a 17WSM AR in person. For the volume of shooting a guy could do and for the hurdles to get a rimfire AR running right, I'd probably rather have a 17Rem conventional AR upper, but for rimfire only areas, the 17WSM would make a dandy rifle (I do have a 17WSM in a remodeled Savage Bmag that shoots sub-MOA and keeps me very happy).
