Last muzzleloader festival was in 1988. I won the uniform competition in 1987, my brother won it in 1988. It was a great event, we had loads of fun. Mike Yeck would bring his Gatling guns out and shoot a hanging picket fence target(inch wide hanging planks).
Mike Yeck owned a range in south central mi. that during the winter we would shoot m1 carbines at hanging clay pigeons and other frangible targets.
