[QUOTE="MTGEEZER, post: 1836301, member: 109472"] TO Sam Summey: re: "roughing up the chamber" response to ROOK57. I have read this thread with great interest as I have a CA Mesa in 6.5Prc and experience pressure signs long before reaching the lawyer load max. loads. I full length resize using Hornady Match Grade dies and use One Shot case lube and wipe off with a cotton towel when done. My pressure signs include cratered, flattened primers and visible ejector imprints on the case base. I am going to re-clean my chamber and clean my prepped cases with an acetone fingernail polish remover and do another pressure test workup. If my problems persist, how would one go about "roughing up the chamber walls" without damaging the chamber? PS: I very carefully set my sizing die so as not to bump the shoulder too much but was only going by feel as I do not have the tools to actually measure the bump.
