Hopefully Wilbur will delete this thread before it gets too far along.
There are many problems with the information presented in that article, particularly as related to the field of "mechanics of materials".
The behavior of steel crystal lattices, beams, and structures are well understood. The atoms of a steel rifle barrell do not know whether they are a barrell, a structural tube, or an I-beam. They will behave in a predictable manner.
Until the differences between all known material behavior and Bill's vision of how barrells behave are addressed on a 1 by 1 basis, further discussion is futile, and will only result in arguments that are not based on factual information.
