Anybody know where I can get maybe a used copy of the booklet or study guide that goes with the Sonoran Desert Institute muzzleloader lab? I think it's titled: "Muzzleloader Lab, 2nd edition, ISBN 978-1-945697-33-3" . I wonder if you can download .pdf copies, etc? I've searched their web site and no dice. Called them, they said no, we only sell to students...
