I dip my 06 case necks in a small jar of powdered graphite, tap once or twice to get the excess off before neck expanding. This helps the sizing go a bit smoother and eliminates the awful screeching that usually results without it. Also reduces the wear and tear on the expanding ball. A small jar or vial of powdered graphite lasts a very long time. It is a bit messy, but worth the effort to lengthen the life of the expander ball and keep things quieter. J. CooperInformation
