I have done it, but not recently. I believe I have 2 boxes of 25 loaded and ready for firing. The brass is Brass Extrusion Labratory Limited (B.E.L.L.). It takes a Large rifle primer. I loaded them with some hand made tools, a 12 guage Lee (Hand) Loader and some help from a M.E.C. 650. I used 700X powder, #8 shot and 10 ga plastic wads ( that's right, 10 ga.). I sealed the top with some old paper cardboard wads glued in with a large amount on Elmer's Glue (which actually hardens and holds the whole thing together). It was a long, tedious process (for me at least) and I do not think I will do it again. Quantrill
