Will it survive? That's a tough call. If by "survive" you mean be around a decade or more in the shadows, I'd vote yes. If it means flourish like the .22 LR or even linger like the .22 Hornet, I'd say no. It's a niche cartridge and will (I think) always lead a very shaky existence. It certainly doesn't help that the first rifle offered for the big launch (Savage B Mag) is a real dog - nice price point (the Ruger 77/17's will be $1k+ when they hit the shelves up here) but oh my, what a sub-standard Savage product! Seeing the difficulty in finding other rimfire ammo right now, the current (and perhaps temporary?) popularity of the 17 WSM is due in part to the availability of ammo. If it's hit and miss on finding ammo, new rifle sales will be the same. If/when some better quality new rifles come out, they'll be a surge in popularity and the ammo hoarding will likely empty the shelves and halt gun sales. I guess the life of the 17 WSM will be like a slinky with rifle sales on the front and ammo availability/sales on the back constantly stretching out and then suddenly catching up/stopping progress.
The 17 Hornet is no doubt a great option in a similar niche, but chasing reloading components is not much better than finding factory ammo right now. And some (myself, for one) have time to either reload
or shoot so the rimfire option is attractive. With the fairly limited options in .17 bullets and the fact that coyotes are high on my list of prey, I'd prefer the added horsepower and versatility of a .22 Hornet anyway if I had the time to reload and chase components.
So all that said I just ordered a B Mag. My reasons? I had a new rifle itch to scratch and want a handy little rifle for cruising this summer and popping some varmints. The 17 WSM is too interesting to not try, even if the B Mag is a bad gamble. I would have bought a nice .22 mag instead, but can't find any ammo at all... anywhere... so that was not an option. I don't want another rifle to reload for (re: the time thing) and there seems to be a decent supply of WSM ammo around me so that fueled my decision.
I'll do a review on the B Mag once it's in and I've done some shooting/tweaking. Then I will tell you if the 17 WSM is going to survive... in my home, anyway. LOL!
