Honest answer. I have no idea why. I prep brass, seat primers, charge powder, seat bullets and then shoot guns all day, or night as it is now. I have zilch to do with what and why we make what we make. Occasionally I get in on some R&D projects, trouble shooting, etc. I know this. We are running balls to walls, 24/7, at least Mon thru Friday with an extra 12 hr day crew coming in Friday through Sunday.
