So here are few answers to questions, brass is new full length sized and trimmed. There are no scratches on the casings. What I mean by a stiff bolt is it is stiff to lift the bolt not extract the shell. The bolt moves rearward with great ease. I did try the suggestion of lifting the bolt with the firing pin compressed and released and it does require more effort to lift the bolt once the the gun has been fired but the effort required after actually shooting a round is much greater, but there is a significant diffference. I will check out the two posts I believe MrFurious provided to see what I can find. Am I getting closer?? Thanks to everyone for your help, this is a great website with a ton of helpful folks.
