Just for the record 9.3x62 brass is about everywhere, I get Norma, Lapua, FWS and HDS from Huntingtons, Midway and a few other places, and you can make it by simply running a 30-06, 280, 270 case through a 9.3x62 die that has a tapered expander...bullets are easy to come by...

The 9.3x64 brass is presently available from Huntingtons.
