Welcome to the fold... You need roundballs from Speer or Hornady (or Warren) in 457 diameter. You need Remington #10 percussion caps. You need a lube like Bore Butter. Suggest 45 Caliber Ox-Yoke Wonder Wads. A capper, snail type or in-line is handier than using your fingers to cap. A snail type will hold a whole can-ful of caps. If your Ruger came with a nipple wrench it also has a blade on one end for turning your cylinder pin and rammer lock. If not you need one, or a screwdriver and a 3/16 inch socket driver for the nipples, so you can remove them for cleaning, etc. You need a powder flask with spout for 30 grains of powder, and spare spouts for 25 and 35, even 40. Of course, you need 3fg Black Powder, GOEX if you can find it. Alternates are Pyrodex, which is a form of black powder, Cleanshot which is smokey but not smelly, and dot as corrosive, and Hogdon's 777 which is very much cleaner, also smokey, easier to clean, but stronger. a 35gr charge of 777 is a serious load. Incidently, ONLY black powder really weighs (close) to the powder settings of a measure. Pyrodex, Cleanshot and 777 must be measured by volume, not actual weight. Hogdon does have a chart on Pyrodex, a weight factor of 1.33. Lots of books and articles on the loading and shooting of black. Lyman has a good manual. Go to Ruger's website and download or order the Old Army Manual.
