I have a 4 cavity Lyman 311403 that has some rust pitting in one cavity near the parting line. the bullet usually has a small bit of lead protruding off the side of the flat nose, just a little to thick to easily scrape off with my fingernail.
Has anyone ever tried to fill pits with anything, like Liquid Steel or a Devcon product, and had it stay on the mould with the high heat involved ? Would the hot lead stick to a metal filled epoxy product?
