Can anyone identify this mold? The only markings are shown in the photo. Approx. diameter is 0.59". the point(or lack of) is what has me puzzled.

shotgun slug mould!?!?!?!?

Slug Mold or.....Hollow Base 50 something odd caliber or larger Blackpowder mold

Try posting your pics over on the Castboolits Forum, someone over there should be able to identify your mold.

I think it is a hollow base black powder mould. Probably for a 58 caliber.

58 caliber Minie ball WC mold. Probably made by Rapine.
