Bronko, all I use for round balls are Lee molds that I have in .54 and .58. I've probably cast over 2,000 balls from the .530 mold with no problems. The Lee mold leaves the nicest sprue cut off of about any mold. It leaves just a little flat spot on the ball - no protrusion. I firmly believe my cast balls group better than either Hornady or Speer swagged balls.
