This is a custom 10 cavity (banger) mold. Maker unknown comes with heavy wire wrapped wood handles. Keith style bullet is cast .408" +/-.0005 with a weight of 200gr. This is a very large mold and was used for a rifle (.401 herters) and not a pistol. I do now know of any pistols that take a .408 cast bullet but they might be out there. Looking for $175 shipped on this conus..pics upon request.
