I have one the same way except the threads are loose in the butt socket and the bolt is froze/rusted to the wood. I have tried an impact driver and soaking in light oil. I have not given up yet, but breaking it free without messing up the stock is going to be a job. It is like the wood has swelled around the head of the bolt. Locked it up tight!
Very helpful to have it in a padded vise...cushioned jaws holding the buttstock.
I had a tough time getting my stock off too, but I tapped it around gently a bit after letting some lube sit on top of the screw for a few minutes. use a soft piece of wood covered in a rag in direct contact so you don't damage your stock and it might loosen it a bit more in order to get that screw to release.
I have removed one or two butts from rifles that were pretty rusty. We had a tool called a BRACE, Armourers, stock and a long big steel bit called a BIT, Armourers stock bolt. These are the proper tools and I've never encoultered a stock bolt that didn't budge with these, even after they'd been used in the saltwater mangrove swamps for months on end.
Go at it with a bit of brute force and ignorance.
And here's a lesson for you all. For gods sake, liberally coat the stock bolt and the thread with lashings of axle grease (we use GREASE, XG-279). ALWAYS protect the metalwork under woodwork with grease
