Ruger has not chambered wsm calibers in 4 or 5 years. Maybe longer than that. I read that they quit chambering wsm's because they did'nt want to pay royalties or something. Some legal dispute. The only one I saw was in '06 on a hunting trip to Idaho. It was stainless/synthetic and chambered in 300wsm, nice rifle. Anyway I hav'nt seen one since, so I ended up with a Kimber. Those rcm's do sound like cool little rounds though.
