[QUOTE="One_Duck_Limit, post: 531186, member: 13320"] Thanks for all the advise. Last night we polished the chamber with Flitz. We figured if it needed to be re-chambered we might as well try a quick polish job. We did as much reading as we could find on polishing a chamber. From all our reading we gathered super smooth wasn't what we wanted. We attached a 20 gauge bore mop on a cleaning rod, chucked it in a drill, applied the Flitz and spun it in the chamber for 30 seconds at the most. We test fired two shots. The first was a normal load and the second was hot. Both extracted with minimal effort and neither case had marks in front of the belt. Tonight we are headed to the range to test more loads. At this point we think there may have been a burr in the chamber where it transitions from belt to case wall. Has anyone else had issues with burrs? The reamer is brand new and it was chambered on a manual lathe. [/QUOTE]
