What exactly was your problem, was the case hard to chamber and jammed? When I got my 300 win mag BDL I had a hard time chambering the bullets and the cases jammed. It turned out to be a rough chamber and I had it sent back and they just polished the chamber and I haven't had any problems since. Like everyone said, the extractor won't go over the rim until the bolt is all the way in and locking down.
