Frustration meter has pegged. Cast up a large quantity Lee 452-255 RF and went to start sizing. Seemed like they were being sized unevenly. Thought at first it was the old Lyman 450 I was using but tried the sizing die in two other sizers, another 450 and a LAM II and still the same. Started thinking maybe it isn't the sizer so grabbed a micrometer and checked, as cast diameter varied from .4525 down to .4505. Looks like the Lee six banger is way out of round. Mold was bought used years ago and this was the first time I used it. Shame about the mold, it dropped bullets out with barely a tap on the hinge pin and I ran over 50# of 96-3-1. Looks like I need a new mold.
