[QUOTE="Gene, post: 364831, member: 7402"] I know nothing about the H&H. I have a Holland concentricity guage which is much like the Sinclair. Bought a Bersin some years ago. It does measure concentricity, but they tout its ability to straighten bullets. The bullet can be moved somewhat after seated, but all you are doing is stressing the neck, so the next shot from that case is even more exaggerated. I sold lit. Cases come out of the sizer die lacking concentricity and that is where you need to start. You need to remove the expander plug if you use one. Either use bushing dies or have a custom die made for a good chamber fit and you can throw away the concentricity guages. Send Harrell's $70 and two fired cases, and they will make you a custom fit die. [/QUOTE]
