I think I would stay with drilling the entire screw head out before cutting the rings and screw in half with a Dremmel. I seem to be blessed with having the cutting wheel getting in a bind and "jumping" somewhere I really don't want it to be.
The screws that I had a problem with were in the receiver, holding the base to the rifle. I tried a bunch of things such as soaking, break-free oils/lubes, etc. I'll stay with the Torx bit or allen wrench along with heat.
