Dave, thank you for responding. Your insights are valuable to me. I think I am fortunate in three of my rifles have good chambers in them. Two are Bob Green chambered and fitted PacNor barrels and I have little runout problems with the two of them. That of course is shooting fire formed LC cases in the 223 and 20 Tac.

Your idea of rolling on glass or metal to find the cull pieces is a real time saver along with components.

I thank you again for sharing as it is very helpful.
