A Lee .360 dia round ball mold for my 38/357 hand gun . A Lee .430 dia round ball mold for my 44 mag hand gun.. I cast from pure lead BRN 6 & coat with Lee's liquid alox. Let dry & seat in a well bell case mouth with the flat from the spru cut seated straight up or straight down. Loaded between 600 & 700 fops. Great fun. You should be able to get a mold that is close. Not rocket science. If absolutely necessary push thru an appropriate size sizer then coat with the Lee alox.
