Thanks for the input. I thought about removing the action screw boss, but if I did I would loose half the threads for the screw. The boss has to stay. I thought about a "real" lug between the barrel and receiver also but if you look at the pics of the stock you will see a bulkhead between the forearm and the aluminum insert. This is where the receiver and barrel meet and the bulk head would have to be removed and I'm not sure what that would do to this stock? On careful inspection of the tang, there is a very small gap between the receiver and the stock, but I'm not sure about the action screw boss and the lower tang inlet. There does apper to be evidence of rubbing on the sides of the rear boss. So it appears that *maybe* all the recoil does actually get transferred by the front action screw boss.
Right now plan "A" is to get a piece machined to replace the existing aluminum lug with a SS one that will fit into the slot under the receiver and relieve any load on the boss. I wonder if pillars would help in this stock? This may be a plastic stock, but it is grade "A" sewer pipe material. It is very rigid and I dont detect any signs of compression. When holding by the grip, I can't noticably twist it by trying to manually torque the forearm.
Plan "B" is a custom inleted McMillan stock with a "real" recoil lug and pillars.
Plan "C" is a custom match grade Lilja 3 groove barrel in 6.5mm-WSM
Thanks agian for all the input and if anyone thinks I'm nuts dont be shy to tell me
