Thanks for all for the input.  After recleaning the chamber area, I just could not see or feel any burrs/raised spots that would affect headspace.  So, I started to think "out of the box" and decided to take the action out of the stock (maybe the bolt is touching the wood).  I also looked for clearance on other surfaces of the receiver that might come in contact with the bolt.  I just wasn't seeing anything.  But then, something did get my attention.  Please see pic #3 and note the clearance between the receiver and bolt.  The gap looks tapered.  Is the receiver bent or torqued?
Thanks again,
