I have a 2 cavity Lyman (so marked) mold 311410 which has a center to center of the boolits .480+ or -. My other Lyman molds have a spacing of .440. This does not seem like much but it puts the holes in sprue plate a good ways off center. I did find an old (one of the old thin ones) which fits this mold. Just wondering if anyone else has had this problem.
