My redding bushing (neck) die is giving me .002" runout on my cases. They come out of my chamber at NO MORE than .001". I polished the expander ball slightly, and it fixed some of the cases, but amny still come out at .002".. Whats going on here? Do I need to remove the expander ball all together? Loosen the decapping rod lock nut, and then retighten after the downstroke of the press to center the expander ball? Thanks for any help.
