Trying to mount a base to new short action Savage with rounded receiver and one of the EGW picatinny base screw holes is apparently a fraction of an inch off and I stripped the allen head of the base screw trying to set it. I was using a torque driver set at the suggested 20 pounds, so it stripped with less than 20 pounds of pressure. The screw metal can't be too rugged. What do I do? I don't want to make it worse. There is a small amount of the screw still above the base, so I was thinking of taking a narrow file to the head of it to maybe get a small flathead screwdriver on it. If I can get it out I'd probably just open up the base hole a fraction to allow the screw to get seated. Are there any special drill-bits that they might have at the local hardware store that would allow me to back it out, or drill it out? Any chance that I can locally find a screw the right length and thread if I can't find a way to re-use this one? This setup is brand new and I'm aching to break in the barrel and start load development!
