Thank you for the input. I don't know if it was due to taking the extractor out and replacing a lost ball or not, but I put the bolt back together with the new ball and chambered the two rounds that messed me up with no problem. Mr Coody seamed to be on track with buil up in the extractor itself. Thank you all for your help.OldShooter,
Have you tested with another brand of brass (Lapua) to see if you get the same resistance? You could also have a bad batch of brass in which the body is not properly sized and needs to be run through a Body Die or Small Based Die. Tight chambers will do that when the brass is liberally fat or the shoulder angle is out to lunch. Just something to consider.
