After doing some more research this evening it dawned on me that since I'm planning on reloading why not get a 260 in a long action so that I can load the 140/142gr bullets further in the neck
If you have a Savage long action, you can get barrels in 6.5x55 or 260 for a lot less than the quotes you have for a custom build.
Also you could consider the 6.5 Creedmoor.
