Here's and idea, take a look at the 30 BR (assuming you handload). It uses about 30% less powder than a 308 and pushes a 125 gr bullet to within 130 FPS of a 308. It is competing very well against other LR cartridges on the lines out to 300 (big time accurate), kicks A LOT less than a 308 (feels like a souped up 243 to me), and is very easy on the barrel. I used to do a little BR before discovering plates and pins, and a couple of guys use this cartridge at 300. If you are using it for deer hunting only, it'll last thru several generations if maintained, and lay those whitetails down way out there if you are shooting those Nosler 125 BT at 3050.
I bought a 7mm 08 for the kids, and really wish that I'd have bought a TC custom chamber 30 BR instead.
