I know this has certainly be tried before, but never heard about. A cartrige using a necked down .44 mag case to fire .357 bullets shoud be a dandy in a .92win. actioned lever action like a puma, falling somewhere between a .357 mag and a .35 rem. powerwise, would it not? Any sugestio on which powders to use? Your opinions will be much apreciated. Thanks in advance.
