RE: 308 or 270
IMO it depends on what type of hunting you do. It is obvious by your posts that you know how to use a rifle. I do think the 308 is slightly more accurate. If you are wanting a carry rifle I would also give the edge to the short action. I definitely prefer the 30 caliber. but then I have never been a fan of the 270, I have a fondness for the 30-06, even if it is not the "COOL" cartridge. And as you said, the 308 definitely has the bullet selection edge.
It sounds like 308 to me. Tom.
