My father's .375 JDJ Contender barrel came to stay with me. He only loaded & shot jacketed bullets in it. I plan on shooting cast Lead. I have brass, dies and an assortment of powders. I am looking for a recommendation for a cast bullet and loads for it. I do have one plain base Lyman mold of about 300 grains. I might hunt deer with it, but am more likely to shoot at targets.
