To be quite clear, it only happens about 4-5 times per 100 rds. (US-made brass), so far. This is just a Range gun, and even though the 'new' extractor just arrived from "Jack's First" ($50 with shipping), the extr. Claw is not as long as the original (how can a shorter one be better? Both have straight, clear edges), so I decided not to use this second extractor. Having never polished any chamber, and with no vice available, would Flitz help if applied on whichever part in my Dremel? Never used Flitz at all, but even guys who have serious extraction issues in guns (ARs or handguns with a chamber burr) claim that it can help when applied on a patch etc for a drill.
