I am considering the 270, I am already having 2 built on 700 action but I don't think a stock action will come in at the 7 lb mark even with an edge stock
Had mine built in the mid 80's. M700 custom syn stock 30-06 no metal work other than matte blueing. With Leupold 2-7 Compact and sling 7lb 2oz. Of course today you don't have to go custom and can buy lots of them off the rack.
