Don't cut it. You will end up with a long action 7mm-08 and not save much weight. In my humble opinion, The entire reason a 280ai exists is to try and replicate 7mm rem mag ballistics in a non-magnum action. Why go the other way with it?!
Save the money trying to tinker with this gun and put it toward a short action lightweight 7mm-08. Now you are getting a true weight savings (1lb +) and not creating a hybrid gun that is trying to be something it isn't (lightweight or fast).
