Thanks for the reply. here are two photos of my Lightning. According to the serial number manufacture was in 1896. It's got a good bore and the feeding is positive. Quite hair raising to try, though. Especially inside a gun shop but I had to know. There were no dummy rounds and after every racking of the action you need to pull the trigger before you can rack again. White knuckle stuff, particularly for the thumb hanging on to the hammer. I had a chat with a big Colt collector here in South Africa 2 days ago and he claims it's not too difficult to dismantle a Lightning - and put it back together again.

) So I think I want to go with the BP load for authenticity's sake. How do you make those lube wafers you mentioned? I guess you melt some lubricants on a tray and cut them out with a case when solid? What's the recipe?
My plan is to take the two Colts as well as my 1873 Winchester rifle, my 1892 Trapper carbine (15" barrel) and my Ruger Vaquero (as a modern comparison) and test the ballistics and ease of handling (pump vs. lever action) I just need to make enough 44-40's to feed them all.
