Oh my be careful with that carb cleaner. The only goddamn substance on the planet that'll kill a cockroach dead in his tracks. Beats the snot out of RAID.
Try lime-away! On the cockroach, not the chamber.
It probably isn't a headspace problem in the technical sense, since they headspace on the rim. If it's a standard refurb, the headspace should be fine. If you're sure it's totally clean, I (hesitantly) suggest a chamber cast. Is there any sign of a burr digging in to any of the brass-cased rounds?
