The 17HMR is well established as it is very popular with quite a few gun makers producing firearms for this wonderfully accurate round.
The 17WSM will not ever be, in my opinion, a big seller. With very little sales, it will someday soon be discontinued and those of you who bought a gun will not have anything to shoot in it, unless you can reload your own rimfire cartridges.
Buy all the 17 Winchester Super Magnum you think you will ever need now while you still can.
here's my 2cents, its a great round, ballistics,damage to varmits, low cost, its a great round!, BUT with only one company making ammo, and limited companys making the rifle what will the long term support be?
winchester makes the ammo, who else?
savage makes the gun(2 models one blue and one stainless) winchester makes 1 gun(1885 low wall and the only one on gunbroker is 1350.00)
till i see more support from the gun industry, ill pass on the .17 wsm
