After reading my post a clarification is in order. I do not doubt that Ackley fired the 94 winchester without a locking bolt. What I do question is his claim that it was made possible because of the improved chamber. Note he didn't fire an unaltered chamber to show the difference, and his pressure was in the range that a dry chamber would hold either case forward. To furthur prove that the forward part of the case will not hold thrust, only the case head need be lubed to allow it to come back. Or in another way of saying it; The case neck stays forward, oiled or not.
