I'm not sure which round I'd like to chamber my next build for, but have decided I want to use the WSM case. I'm seriously considering the 270WSM but haven't ruled out a 6.5 or 7mm. I'm not too interested in the 300, but if there's a serious advantage I may reconsider. I've run the ballistics and I like what the 270 offers verses all the other choices. Hope to get some serious feedback and real life stories/examples of why one is better than another. I plan to use this rifle for hunting anything on 4 legs I'll encounter in the Northwest (WA).
