I got this mold in a box of stuff from an estate sale, rubber band paper on it just said 38/357
It looks like it is possibly a Keith type 158 gr lswc , hp, and MAY be gas check type, I need to get better eyes on it, but stub looks like it might be.
It is single cavity.. A google search on my phone has plenty of hits to related items, but nothing exact.
Looked on lee's page but could only see dual and six cavity molds, no matching numbers..
Thanks
