Thank you Larry, and I forwarded this valuable information on to Randy Bimson, Director, Technical Affairs, Sporting Arms and Ammunition Manufacturers’ Institute, Inc. He responded to my inquiry as to the origin of the shell box warning back in May. His office is in the process of electronically cataloging SAAMI historical documents, but he then had no knowledge of whether any published statements relative to the safety or use of Pattern Welded barrels exist. He also explained that SAAMI does not currently have a position on the use of smokeless powder ammunition in Damascus or Twist Steel barrels, but added “should you broach the subject with any of the SAAMI member ammunition manufacturers...the response would be unequivocally ‘Definitely not!’” (His emphasis)
