MikeG,
Are you serious about the wobble? I have been loading for a while and haven't tried looking for a wobble. I have however had loads that I have spent a good deal of time on and never worked out any accuracy. Fortunately for me I let the dies go with the gun. This seems very interesting to me. The dies may be partly to blame. Can you give me a source for a concentricity gage? How does it work? Sorry about butting in, I know good info when I hear it! Thanks!
