I have some experience bending our usual SxS stocks but have not tried one with a through bolt. If you loosen it the stock will pull away from the receiver I think. It was suggested to me to keep the bolt tight and the head of the bolt will slide until the shaft touches the wood if the hole has enough clearance.

If someone has experience with through bolt stock bending I would appreciate advice on how to tackle it.

So many guns, so little time!
