Measurements on the mold are interesting to me, but I am not a an expert with vintage rifles and cartridges.

The bottom half [male part] has a recess of .392" diameter and .202" deep. The upper half [female part] has a .443 " diameter at the base , quickly tapering to a point. That recess is .406" deep. This seems to cast a bullet with a shoulder between the upper and lower pieces. It must have been an unusual cartridge to use this shouldered bullet.
