I've got a wildcat question that this thread brought to mind. Someone in my family has a wildcat rifle in the collection, a Mauser action. The brass in the cabinet for it is .300H&H, there's four or five boxes of .404" jacketed round nose bullets in there too. Anyone heard of this mix? It's from the '70s.

My next wildcat will be a Capstick .470, it's unavoidable.
