I have a Crossman nitro venom dusk in .177. One of the screws that hold the stock in place broke. The head came off the screw, but the rest of it is still stuck. I was thinking of drilling a small hole in the middle of the broken screw so I can then pound a bigger drill bit in the hole. Once the bigger drill bit is stuck I would then put the drill gun in reverse hoping for it to unthread. Is this a good idea, or is there another method?
 
Drilling in the center is tricky and hard to do... if you can successfully do that, use a left hand drill bit to reverse it out of the hole... you may also find it will screw itself into the hole and out the other side when you try and drill the center.

Bad idea to try to POUND another drill bit into a hole. Drill bits are hardened and will break off easily, then you are really pooched.

Buy a set of broken screw extractors. They are relatively inexpensive, come in different sizes, and if you can drill a hole in the broken screw, then tap in the broken screw extractor, it will usually let you back the broken screw out of the hole.

Alternately, find a good machine shop that has an Electrostatic Discharge Machine. They can use it to get the screw out.

Always soak in penetrating oil and try to back it out with a pick first. I've successfully done this for people many times, saving them the cost of me machining it. Centering on a small broken screw is challenging even on a mill.
