Okay, I picked up my first black powder rifle last night, its a Traditions Pursuit XLT with a camo thumb-hole stock and nickel barrel.

I don't know much about black powder but my father does. He has been shooting black powder for a few years and I figured this year I will give it a shot. Is there anything I should know about this gun? I am going to be hunting whitetail here in FL, so what powder should I get and which grain bullet?
