Back when I was into killing things, I used to hunt deer with a flintlock, much to the amusement of the "Out of staters" with their elephant guns and bannana clips.
I came out of the woods one day, and this guy said "How do you unload that thing"? I pointed to a fungus on the side of a birch tree,about 20 yards away, and said "Like this" phoom! blew that fungus into a million pieces. he says "Well I'll be damned"!

I also made a revolver from a kit, and the only advice I can give is, take your time. It is tedious and time consuming to do it right, but if you don't, you will not be happy with the finished product. I gave it to my son in law. Patience is a virtue that I lack.
