Also Roger, it's been my experience shooting a 17 WSM for a few years now, that the 17 WSM ammo suffers from the same variance, from Lot# to Lot#, that all other non match grade rimfire ammo suffers from. That's not to say it's crap, but a couple things I'd recommend.
#1 If you find a particular Lot# that shoots well in your gun, go back to that store and buy all of the Lot# you can get your hands on.
#2 I always check POI whenever I change Lot#'s to confirm if I need to make any scope adjustments.
Or, you can disregard all of the above and just go shoot it and where it lands is where it lands. Depending on your expectations, this can sometimes be the best choice.
The thing about the 17 WSM is it is a very capable little cartridge and has the ability to reach out much further and deliver with authority, better than any other rimfire on the market, but because it can stretch out there further and make hits on ground squirrel sized critters at crazy far distances, especially for a rimfire, we as shooters get frustrated when the ammo or the guns we're shooting it in doesn't allow us to do that on a consistent basis.
I've shot sage rats out to well beyond 300yds, but I know Eric w/Varminter dot com has shot ground squirrels out well beyond 400yds with different 17 WSM rifles so that will give you some idea of what these things are capable of.
I recall you considering a 17 Hornet, did you ever get one or did you get this new 17 WSM instead??
