I posted here a while back about the problem I was - and am still - having with my Mosin Nagant M44 Carbine. First, I want to thank everyone who replied on my last thread, and ask the same question again.
The receiver tang bolt on my rifle is stuck. Crazy stuck. I've tried screwdrivers, normal lubricants, a drill, a manual impact driver, and penetrating lubricants. Nothing is working. I don't want to have to drill the bolt out or cut the stock apart, but I'm afraid I might have to...
So my question is this: is there anything I haven't tried yet that might work for me while not breaking the bank? I see no desire to pay a gunsmith the price of the gun just to come to the same conclusions I already have, and I really don't want to risk damaging the gun. So is there anything I can do?

2 things I have done that worked for me is to 1st try actually tightening the screw as this may break it loose then unscrew it; 2ndly an application of heat as from a propane torch-just a bit of it & focused so as to not scortch the wood. After its hot put your screwdriver in the thread and hit the scredriver with your hammer then try unscrewing it.

I doubt you can heat it enough to do any good without burning the stock.
If an impact driver didn't take it out, drilling it is the next step.
(Assuming you had it resting on a hard steel surface with no give to it when you tried the impact driver)

If the threads are just boogered up, you can use a brass or aluminun punch and give it some good whacks. It may straighten the threads enough to get it to move. If it is truly badly crossthreaded you may need a drill. If I remember right those are slotted screws, make sure to use a gunsmith type screwdriver (non tapered) that tightly fits the slot.

Try a impact driver. As you are twisting the screw you impact the tool with a hammer. I have removed some very stuburn nuts and bolts with one. I think harbour freight has them.

You can try using electronics freeze spray found at a place like Radio Shack. Put the bolt/screw in a heads up position and slowly drip a lot of the cooling spray on it using the extension tube while letting it evaporate and cool between drops. This will shrink the screw metal and the stud on the barrel will stay larger due to the larger heat sink area. Then try removing the screw with an impact driver if you have one. Otherwise use a screwdriver by holding tension on it and hitting the top of the handle with a mallet. This will not hurt the wood like heating it could do. This has worked on things a lot of times for me in the past. Good luck with whatever method you decide.

apply Kroil - let sit overnight
repeat the above
try to remove screw. if no joy, then...
put screwdriver into slot - heat the screwdriver shaft not the rifle
when kroil smokes, this is an indication you are getting heat to the screw
next thing is to use a mill or drill press (in neutral!) to apply downward pressure with action in vise. Chuck up a screwdriver bit, then use a wrench to turn the bit.
