RE: 308 or 243?
Another option is the .260 Rem, it too is a necked down 308. It most likely would have a little less recoil than the 7-08 (.280 cal) and 308 (.30 cal). I personally haven't shot this round but every one I have spoken to that has, loves it. It is supposedly a very accurate round and is devastating on deer. The 308 and 7-08 are also great rounds, just throwing out another option.
