Are you sure those are lead headed and not just the washer? I just cant see lead being able to stand up to any kind of torque from drilling into metal (as they are bit-tipped).
If I were near you, I'd give them a go. I bet they would test as pure lead, toss in a little tin and you'd have good bullets. Problem is there will be more trash than lead since the screws are steel. is the screw body zinc coated?
