Hello, I was jsut wondering if these cartridges were easily made. My friend has had a double deringer passed down to him from his grand father and he wants to try it out. First of all, is this a good idea? It's in great condition, stored for most of it's life, but such an old pistol, maybe he just wants to box it up and keep it in as best condition as possible? Can these rounds be made or are they going to be really hard to come by? Am I even posting in the right area of these forums? Thanks for any help given.
