Thanks. You might want to try using heavy and in your rear bag but use beach sand or similar for the ears. In the front bag I'd use just beach or similar sand because the heavy sand can end up packing as hard as a brick and you can start throwing some of your shots. I shoot competition and I've heard many guy's say what I'm saying.
a mixture of chromite sand, glassy slag, and metal. Figures 26 and 27 show pieces of the defect that can very easily be removed, and leave a very good surface finish on the casting after removal. These pieces are, however, magnetic. If one calculates the mass of an equal volume of rammed chromite sand, and then calculates the volume and weight
