Lyman Mustang .50 cal and Blackhorn 209 black powder subititute
Has anyone use Blackhorn 209 powder in a Lyman Mustang Breakopen .50 cal muzzel loader. I just received my Lyman muzzel loader today and tried to fire it. Shot three CCI 209M primers and all fail to ignite the charge. Prior to trying to shoot I had cleaned the barrel and breech plug. Also ran a super fine drill bit through the breech plug. Anybody else run into this problem.
