So is it going by WMR or WSM? When I see WMR, I think of the 22WMR, which is akin to the HMR, whereas the 17WSM is a unique cartridge not related to the 22WMR.

Sounds like the point is moot since LBR got a "Hummer" already, but I'd comment that I'm not quite sure that I think the 17WSM is going to go away. As long as we can get out of this Rimfire shortage, I think it fills a perfect niche that will give it staying power. I'm really sad to see the 17HM2 go away, as I REALLY loved that round - I'd LOVE to have a Ruger SP101 6" or a Mark II (not III, but I'd take it) in .17HM2.

The 17WSM stands above all other rimfires, quite likely at a level that can't be accomplished in heavier caliber rimfires. It still doesn't quite reach centerfire level numbers, but it's certainly far enough ahead of the other rimfires to make a difference.

If it weren't for the feeding issues that I'm hearing about the B-mags, the fact that they don't have one in Stainless/laminate yet, and the fact that I 'need' about 3 other rifles first, I'd have a 17WSM myself!!! (That being said with a 17HMR and 22WMR in the safe already).
