I'd love to know what kind of accuracy can be achieved with the 17 WMS in a single shot Winchester 1885 or a custom rifle. I still believe all the accuracy issues being experienced with the Bmag are ammo related and not because of thin barrels or quality issues on Savage's part. I also believe that's why we're not seeing any 17 WSM ammo out there. I think Winchester is trying to improve the quality of their ammo. If I had the time I'd take a couple boxes of ammo and weight each round unfired and then after being fired. I'd also chrono each shot. I bet that data would be quite telling and vary greatly by box or production run.
