    Skirt base 429421

    I bought a 2 cavity Lyman 429421 off eBay. It was my first mold. It has a seriously rounded corner (on the mold) on one of cavities. This leaves a “skirt” on the bullet from that cavity and some smear on the mold when cutting the sprue. But the bullets seem to clean up OK in the .430 Lee sizer. I like the bullet. It casts about 253 gn with wheel weights. It is otherwise easier to use than my newer Lyman mold for .357.

    Is this normal wear? I do not understand what caused this wear - lead is softer than steel. Second, should I just use one good cavity or clean up on both sizing?

    Thanks for any info.

    It could simply be from someone opening and closing the mould with the sprue cutter closed. This is a no no.
