My first 356-120-TC mold was a two cavity and the mold would drop boolits that measure .358 and my guns really liked it. So I ordered a 6 cavity mold of same design, and it dropped boolits that measured small (.355") I was not happy, nor were my guns. A year later, I ordered another Lee 356-120-TC 6 cavity mold, and it drops boolits that measure .360" and I like it alot.
I hope this info gives you a little perspective.
