At a vintage shotgun show a few weeks back i bought a 1851 and 1861 2 gen navy. No boxes, some papers, but unfired with a mar here and a nick there. I would like to shoot one or both, and never have shot black powder. Can someone suggest a good source to get what i need by internet ( i think this means synthetic powder?), what size lead balls and greased wads, and maybe suggest a little instruction e the lowding process and post shooting care of these revolvers. Thanks.
