Psteinmayer, I appreciate you're taking the time to write. I am seeing my primers are backed out 10-15 thou. They don't look particularly flatted, just backed out. Not sure what to make of that. There does not appear to be a crimp mark on the heads so they must have thought it not necessary. Maybe that is a requirement only for ammo shot from semi-autos.

Could this be due in part  the result of my not cleaning all the oil out of the chamber and the brass not gripping the chamber wall enough? Not sure of the mechanics of a rimmed cartridge when it comes to primers backing out.
