Chamber honing & polishing isn't a job ( to do it well) for a hand drill... they will remove metal ( but sometimes not an equal amount from total circumference of the chamber, meaning..."you are left with an oblong chamber") to loosen case head binding if enough time is spent at it. but won't "polish". you need very high speed (Dremel type speed) and use oil on your very fine (like 1200 grit, hard to find unless you have a specialized metal finishing store close by) grinding tool to end up with a polished finish.
Tight chambers may not be the problem. The extractor would jam in place so tightly that I'd have to smack it with a drift to get it to move. I mean--there was ZERO tolerance there! I measured the extractor and its seat with my caliper--depending where I measured, there was + or - a few thou. I removed it and dremelled both ends/sides flat, and took some emery to smooth the shaft a bit. It's much better now. I'll get out to the range next week to see how much difference it made. I'm hoping that's The Fix....
