go to google.com (or whatever search engine) and type in "Ruger Old Army" and you will have enough to read. it is made for up to 40 gr FFFG, and round ball .457. Have fun, email me offline, I can send you some more articles and such collected off the net.
You have the finest of all black powder revolvers, no doubt. Mine is a blued 7.5".
Not sure about the hair trigger, but mine is new, (never shot before I owned it, though it was NOS on the shelf for a few years). My trigger is light, but not THAT light. and also, go to ruger.com and download a current manual for it, (its a lot more than 4 pages now!!
