I'll start off by stating that the next build I do will be in the 6.5mm family. However don't count out the 270 WSM. Alot of the performance will depend upon how long of a barrel you are willing to carry. I had a 270 WSM that would actually push a 130 grain Barnes TSX at 3500 fps, measured by 3 chronos and. MagPro is absolutely the best powder I found for this particular cartridge. Several long range kills with that one. Just food for thought.
