I bought a "as-new" model 112 varmint stock from a member here. It is a beautiful stock. But I am having a problem. When I put the action in the stock and tighten it down, the bolt will only turn approximately 25% of the distance to full battery lock. It is confirmed that the bolt is not touching the action on the way down. I figure I am getting some contact in the trigger area but I can't see where. Before I mess something up, I figured I would see what the experienced people suggest. Anyone have any advise?
