Mike, thanks for the info. I have an RCBS 3-die set which has an expander die as I was able to load the rounds. It has a full length sizing/decapping die, however, the base of the case is not resized completely because of the shell holder. As a result the round won't fully chamber. I can close the gun and force the into the chamber. I have an A-Zoom trial round/snap cap in the 9.3x72R that easily chambers. It has been suggested that the gun can be rechambered but given that the round is semi-obsolete I doubt anyone would even possess a chamber reamer in that caliber anywhere. Regards, Doug K
