If you really like the Rem700 CDL, then look at the 7mm-08 Remington version. It's merely a 308 Win case necked down to 7mm (0.284"). It'll give you just about the same energy of the 308 Win but will shoot flatter and kick a little less. And it's a short action. I don't think that you'll be disappointed with the 7mm-08.
