If you go to walmart they carry "the complete hunter" Muzzleloading.. Its a good book or better yet, check ebay for it.
Rick Hacker " the muzzleloading hunter" Great book.
The book of buckskinning is another great book.
Im more into reading about mountainmen-fur trade era so im not sure if you're interested in that kind but just incase i'll list a few:

Hugh glass,mountainman Left for dead " Robert M. Mcclung. Thats one of the best books ive read to this day.

Jim bridger, mountainman, Stanley Vestal

Broken hand Fitzpatrick, Shannon Garst.

Thats just a couple i recommend, I dont want to take up your entire post lol.
I'd buy the book by rick hacker first, thats a great book and covers everything from flintlocks to 6 shooter blackpowder pistons to blackpowder shotguns.
