In my opinion, the .308 is great for all whitetails and muleys, but when you get into bigger game like elk and moose, it does not have the downrange energy needed for clean kills. If you HAVE to use the .308 on a moose, you'd best use a 180 gr bullet. Soft tip like a remington corelokt would be good. That's just an awful lot of animal to be hitting with so little gun. Moose kill more people every year than bears do. Are you sure you want to hunt them with a .308? I'm surprised that nobody else said as much
