Reggie:Saw your post about 1 hour after you posted it. I have been looking several times today. I know what weapon fired your casings. Thanks so much for taking the time to make the measurements and the pictures. Before I give you a proper answer I need to check your measurements against some tables. It's 1:00 am here and I'm a little tired. I'll post the answer by noon tomorrow. It's pretty interesting if I'm correct and your pictures did it.
Until then,
Dave
