All true above, and all my guns are freefloated. But I have seen by one well known gunsmith, that if the forearm is properly bedded, I mean very good, even contact between the forearm and the barrel, this rifle can shoot better with the smaller ultralight barrel than being freefloated. Problem is most factory rifles don' t have this nice bedding. Its usually very crude or a big piece of metal with upward force. He showed on an oscilloscope when smacking a barrel with a object, simulating barrel whip, that the vibrations went down considerably. Kinda like striking tuning fork and rubbing your hands up it. Most competition shooters have 7lb barrels also.
