I do quite a lot of Muzzleloader shooting and Homeless joe is right.Use Black only and 2 F with about 2 3/4 dr or 80 grains is a nice moderate load that will kill birds and break targets.
Always wash the bbls out with soapy water,dry and oil after each use. If wads arent available use my 5 and two technique. 5 squares of Toilet paper over the powder and two over the shot.Works just as well except the paper in the air.
