JimG,
Welcome to Greybeard. If you go over the posts on greybeard, you will discover a lot about blackpowder shooting - and that there is more than one way to put a round ball out the barrel.
Lyman does put out an excellent book, and it is necessary to read a bit - especially the chapter on black powder safety.
I would also go to the range and talk with some of the traditional rifle shooters. They like to talk about their rifles and shooting, almost as much as making smoke.
Don't get fustrated, there is a ton of help waiting for you to ask a question. And no question is dumb, what's dumb is not to ask.
Most of all, have fun and enjoy your time at the range and in the field.
