Although it is not exactly what you are looking at, I love my 930 spx and have no problems with it with all different sorts of loads (target, 00, high/low brass, steel, 2 3/4 and 3, etc.) even when mixed together randomly. It will shoot as fast as I can, so no problems there.
Now, I did clean it well before ever shooting it and clean it after every session, but I do that with pretty much everything. Disassembly to clean is straightforward.
In short, I love mine.
