Yes Tex, it was a great day for those who want a 9.3x74R in a bolt action rifle, the 9.3x62 packs a very big Wallup.
Sorry to hear about your drilling, was the rest of the combo SXS 16ga???
Two of my African battery.
I've left a message for Dave at CH4 to see what brass can possibly be used to form the 450/400 Black Powder Express case, dies most likely will run aroung $200 for a three die set. Huntington will be up there too.
One last thought the swiss have a cartridge the 10.3 x 60R Swiss, it might be this same cartridge but under another name, might be worth checking out, that cartridge is still available through RWS.
