I am thinking of rebarreling my rem 700 in either 6.5-06 AI or 280 AI. I want a rifle that has good accuracy and can take large game (elk, moose, etc.). I don't really care about making the brass, just concerned about take down power. Are the 6.5 big enough for elk and moose?? This is the only thing that is holding me up on my decision. I really want a 6.5 calibar.
