RE: 308 brass for 7mm-08 reloading?
That's all I have ever used for my 7-08. I picked up a can of match military .308 cases years ago from a friend and use them only for my .08. I do run them through the trimmer before the first reload and cut them to 'trim length', but only so I'm starting out with all the same brass. I also have a .308 that I load for and I make sure I NEVER use match brass for the .308. That way I never have to worry about picking up the wrong ammo since there's no .308 or 7mm-08 headstamp.
