I have a Savage 340 that has a mangled ejector spring and will not eject empty cases. To replace the spring I need to remove the ejector pin. The pin has a head (arrow in photo) that prevents is from being over-inserted. I assume the hole goes all the way through the receiver, but the other side of it is covered by the trigger assembly which is not made to be removeable. Any thoughts for how to convince this pin to come out without disassembling the trigger assembly to get to the other end of the hole and drive it out? I thought maybe some penetrating oil, let it soak, then hit the receiver against my workbench with the pin facing down to see if it will move, but that hasn't been successful yet. Any ideas or recommendations will be welcome!
