Recurve, I also have a Ruger old Army, and love it. Very accurate. I used to have an old Remington with a brass frame. It gets dirty very quickly, and is a pain to keep clean. I just quit bothering with it, till I traded it. I also have a colt police, in .36, that I really like, as well as a TC Hawken, and a Navy Arms 12 gauge shotgun. I always, used bore butter, or other brand of lube, or Crisco, when the other stuff wasn't available. But like Dane said, always, always, always, clean it as soon as you possibly can. Black powder is very corrosive. I don't know about the non sulphur stuff though. But real black powder , has sulphur, and salt peter, or potassium nitrate, and when, wet, sulphur makes sulphuric acid, and it will rust immediately. Plus the potassium nitrate is a salt, and it too will aide in the rapid rusting, as it draws moisture. I always, used hot soapy water, and run a brush down the bor, and into the chambers, after removing the nipples, and soaking them, in the hot soapy water, and then rinsed with very hot water, and when dry, ran a rag down the barrel, and chambers, to check for residue, and then oiled it well, and ran a rag down the barrel, and cylinder chambers, again to make sure the oil didn't loosen up some residue, to make sure all the residue was out. Stainless nipples are good. But don't be fooled by stainless, as being rust proof. When stainless steel comes in contact with black powder, and the humidity, or moisture gets on it, it will rust. But unlike blued steel, that will be covered by surface rust, stainless will pit! Make yourself a nice little leather bullet pouch. For my Ruger, I used a .44 magnum, or special shell, to load the chambers. I made a stand also, and you can see one in Dixie Gun Works catalog, or on line. Go on line for Dixie Gun works, and look for the Lee black powder moulds. Excellent moulds, and reasonably priced. Plus you get the handles with the moulds, unlike the other brands. The round ball moulds are made by placing a carbide ball in between two aluminum blocks, and the blocks are squeezed together, by lots of tonage of pressure. this gives a much more precise , and smoother mould. They also make a conical mould also. But I have found the round ball to be better in the guns I have. They run in the neighbor hood of around $25.00 per set. Have fun, and enjoy, just be very careful with the black powder, and be aware that static electricity, can set it off. And they are right, it is very addicting !
Next thing you know you will be wanting to build a Pennsylvania rifle, or pistol, in fifty caliber, with a flintlock.
