If you don't like the 270 WSM, I would also look at 6.5 SAUM. No matter what you choose in the WSM and RSAUM brass line-up, brass availability and price will be very significant.
The GAP 6.5 SAUM4S is meant to run at ~55,000psi so you don't lose as much throat/barrel life as you would with the others.
What twist is the current 270 WSM? There are actually some decent bullets available for the 270 in the higher weight ranges. For target work, I use the 135gr SMK, but the 140gr SST, 130gr Berger Classic Hunter, Berger 140gr VLD Hunter, and a few others have decent BC's that when combined with the speed, are good performers if you have a 10" twist.
Based on what you have to start with, I would lean to the GAP 6.5 SAUM4S, blueprint the action, and get a Bartlein barrel.
