I've had my HB SS Bmag for a couple years now and though there are certain things I hate about it, mostly knit picky personal things, I certainly can't complain about how it shoots. I bought mine before they came out with the factory heavy barrel laminated stock models so I tossed that plastic POS mine came with in the garbage on day one and put it in a Boyd's pro varmint then had it bed.
If you are looking for a rimfire with more "pop" than the 17 HMR delivers or you are hunting in an area where you can only use a rimfire but still want maximum deliverable energy, the 17 WSM is for you.
I know you didn't ask but I wouldn't overlook the 17 Hornet either.
