Here is an update. I tried some CCI .38 shotshells. As expected the aluminum case split at the mouth but there was no sign of any other problems. I ordered some .357 max. brass and expect that they will fire form ok.
In the rifle barrel I shot some .22 short, LR sub sonic and LR high speed all worked well. In fact I was surprised by the accuracy (for me) that I could get. It is very consistent.
I have not been able to find a source for the Magtech 9.1mm brass, which I think would be a close fit. Magtech sells only through dealers and all of my local dealers say that their distributors don't have any and a order would have a minimum of 500. If any of you know of anyone I could try please let me know.
I am going to post on the German and Austrian board to see if any one can help ID this gun.
Again, thanks to all. I look forward to any new info.
