I was in a gunshop this morning and happened to notice a 1909 Argentine Mauser that had been rebarreled to 9X63 or at least that is what was stamped on the barrel. Not too bad of a looking job on the entire rifle. The guy behind the counter had never heard of that caliber either. Of course the ever present onlooker insisted that I was reading it wrong and it was a 9.3X62. We tried looking it up in Cartridges of the World and nothing. Just wondering if it was a off breed wild cat, mismarked or what? Would definetly do a chamber cast before even thinking about shooting it. No dies were with the rifle either.
Thanks,

It's listed in the 4th ED of COTW. There was a family of 63mm rimless rounds at one time but they all went by the wayside. Case length is the same as the 30-06, with a slightly longer body length and a more abrupt shoulder angle. It's similar to the 35 Whelen.

brenneke case?

that is, the x64 case opened?

The Swedish millitary had a test cartridge many years ago called 9x63, it would been fine if it enterd service though, a .35 whelen in army disguise if i dont remember wrong, bur cartridges of the world(another bible of mine) has one listed.

I believe Brennekes came about in 1917 or so, I think the 63mm's were a bit earlier.
