I thought my extractor was working fine, but the FTE problem returned. I carry everyday, while working in the yard, on the cars, while cutting firewood, gardening, plumbing and tilework and any other activity I am involved in. Since I can shoot on my property, I often run a rounds through while in the south 10 and seldom clean the Kimber Ultra. Yesterday while running some WWbox 230grs, I once again had failure to eject problems (consitently_ This morning I stripped the slide and looked things over. I cleaned the parts, the extractor looked in great shape. It seems that the internal extractor is a bit sensitive to filth and grime. As the case head slides up the breechface, it continues to pack the dirt, grease and sawdust into the extractor hole until the extractor hook's grip is comprimised. The action of the extractor seems to suck in the dirt and pound it into a slate like coating or 'plaque' in the extractor pad/ extractor hole. Obviously more tension on the extractor won't solve this problem, nor would I think it would. Cleaning seems the easiest solution, but seems rather drastic. Has anyone found a way to keep the crud outa the extractor hole or reduce this plaque build-up. (Blue Painters tape, tissue paper?, flap holster [yuk] non-tacky grease? ) Before I get lambasted for a troll, or stupid post, please understand that I am serious and wondering how this problem might be solved.
