Mr B: Personally I only undertake repairs or restorations to original military standards as guided by Capt. Laidlerand other experts on the Forum. These experts have repeatedly stated that no accurizing techniques have been found by the military to enhance accuracy beyond the standard fitment. Pure target shooters have a different perspective and have tried many things. You might want to buy the book on accurizing by Forum member RJW who concisely summarizes the options (including "bedding"). He also points out that MOA precision is rarely achieved even with heavily modified rifles (unless I misunderstood) while you've already exceeded that goal with your free floating sporter................
