I have to back Mac on this one. As for the WSM line, not sure if the 7wsm will survive, but the 270wsm and 300wsm will be here for the long haul. Rem. is offering it in 7 or 8 models.(270wsm) And look MidwayUSA at the number of fac loading availible for the 270wsm today compared to the 3 or 4 just 2 years ago. Ibelieve it's up to 17 differant loadings. Not a good sign of going under but of gaining popularity. Most every gun and ammo manufactor are offering larger lines in the 270wsm and 300wsm.
As for the 30TC, not really caught my eye yet, they are clouded up with the NEW 308 marlin express in the XLR lever. Lam and SS Yea Baby!!!!!
