Hal,
My security won't allow me to open the photos, saying the "halbucket" has Malware in it,so I couldn't look at the proofs. A 2 3/4" shell will chamber in the short chamber, because the crimp hasn't folded out.Once fired, the crimp will fold into the barrel and constrict it.Whether this is harmful or not is a big point of discussion. If the barrels are marked 8.8 mm, this is the bore diameter, not the groove or bullet diameter.The actual groove diameter in different 9.3x72Rs vary a great deal.Since I couldn't see the proofs, I didn't see if the case length was shown.There were several different 9.3 mm cartridges with different case lengths.
