Thanks for all the suggestions guys.
I think I've settled on a build
I've kinda swayed from my original thoughts of doing a 260 or 7mm. I wish I had a long action. So going with what I have I'm going to build a 6mm competition match with a 24" fluted #2 contour 8 twist on the pierce titanum sitting in a McMillan edge stock with the nightforce 2.5-10x42. I love the 6mm caliber for its light recoil and bullet selection. I think it will fit my needs perfectly.
If I had a long action, the good ol 270 would probably get the go ahead or me wanting something different, the 270 Gibbs
