There are several edited by Sam Fadala and published by Lyman's, amongst others, that are good general guides. Many gunshops have them, and you might find them in a larger Chapters, or google or Ebay "Black powder books" and you may turn one up. Amazon can get you one. Since you're in TO, LeBaron's in Mississauga frequently has Fadala's/Lyman's book, and their price on it is the best around. Al Simmons in Hamilton usually has one and I'm sure Epps does to. $25-$30 depending on where you buy.
