CW it’s not just that but my halves don’t line up perfectly either. Makes for some funky boolits. If I squeeze the mold handles together like I’m trying to brake it I get half way decent boolits. I called lee to see if they could tune it for me but because it’s not in production anymore they passed on it. I’ll have to keep tinkering with it. In the same alloy they out penetrate a Lyman devastator on water jug tests.
