I sent the pics to an antique gun dealer/collector this AM. He told me that he considers the design unsafe in that a hot load could put that breech block into your mouth. You might really wanna have it checked out by a competent gun smith to be sure the catch/latch on that is in good shape and strong. He added that he would not shoot smokeless loads thru it....black powder only is what he advised...short case only. There are some smokeless powders which try to duplicate pressure curves of Black. You may seek those out if you want to reload.

Personally, I have no idea but just thought I'd pass this along...
