how do you get a controlled round feed extractor to let go of the case when the bolt is cycled, currently it will throw 1 out of 3 rounds, the others will exit the chamber stay inside the action ready to chamber again. this is on a kimber with about 25 rounds through it and no, i can't send it back to them. the barrel is cut at 17" and they won't touch it without putting a new barrel on at my expense. this is my first and last kimber. i won't even go into the other issues i've had to deal with. just looking to get this one reliable enough for short shots on big game. it be great if it wasn't a single shot, just in case.
