I done something a little stupid a couple weeks ago and just wanted some feedback.My Kimber Custom Classic was running pretty good after buying some Wilson Mags but I checked the clearance at the top of the feed ramp to the bottom edge of the chamber and it was less than .032".Using a Dremel and a bullet shape stone I machined material out of just the bottomhalf of the chamber but actually removed more material than I wanted to and wound up with about .037". The grinding stone was actually not as fine as I needed and I had to take some 220 grit sandpaper and handsand some of the grooves left by the dremel. I then polished to a mirror like finish with flitz but was unable to get a couple "grooves" out for fear of going too far with my "experiment".They were off center more to the sides of the feeding area so I stopped. it then hit my mind, what if I removed too much,Iv'e heard the term over-throating.I took the gun to the range and fired 80 rounds, 16 rds of which were +P 200gr goldots, 14rds 230gr Golden Sabers with no malfunctions.But I'm still concerned that I may have done a bad thing and it's just not shown up yet. How much is too much in terms of removing material from feed area and was this 80rd. session a fair enough trial to breath easy again ?
