Thanks to Steve Bryson for sharing these reference source data and for the notes on load pressure, etc. They are very interesting to me and must have taken him considerable time to assemble and enter for posting here.

I personally do not have such information available and, without in any way wishing to limit Steve's ongoing contributions, would ask if any others would care to join in -- to locate, scan and disseminate, or better yet, post [assuming no copyright issues] such information here. [Has anyone current access to the cited American Rifleman issues?]

Appreciation again to Steve for his fine leadership to date, and to everyone who has made suggestions and offers of help.

Regards,

Dyson
