Dave, do not know if this applies with your gun but while playing with mine, assemble and disasemble i did notice the barrel and the action getting somewhat caught in the stock. In fact the reciever portion had a single linerub mark along both sides. The barrel seemed to to hanging a bit on the edge of the stock also. From the end of the flutes out to the end of the stock it was floating.... Anyway when I felt the upper edge of the stock (on both sides) there was a very sharp lip (edge)on the stock.This edge did not allow the receiver to sit properly onto the receiver support rails in the stock.As I put the barreld action in and out of the stock I could feel it catch on those edges. When I put the action in and tightened the single screw I could see the action pull down into the stock, but at the same time it did not rest right + you could lift the barrel and pull the stock under the barrel and it did not always go back done where it should. Because of the gun only having one recoil lug, and the rear tang of the receiver does not rest on the stock lip... I am hesitant to float the whole barrel and I definitely want the reciever tight in the stock. Because of these two thoughts my first modification the gun was to sand the sharp edges of the synthetic stock away. What i beleive i accomplished was now the action sits in the stock on the support portion of the stock as well as the barrel. It does not get caught any longer and the rub marks do no appear on the sides of the barreled action.
Still have not shot it yet, hopefully early next week, but i really think this will steady POI. In addition I have a couple of other thoughts, easy fixes,that may provide a even more secure seat for the receiver.
Just sharing some thoughts...
