I have a 358429 two hold mould that is just about big enough. My .3585 push through sizing just touches the edges of the bullets...most of the time. The mould is hot before I start, I keep a thermometer in the lead pot while casting, I try to leave the same size puddle on top of the cutter each time yet when they are cool some get polished pretty good going through the sizer some just push through with no resistance. If they mic .358 I go ahead and use them. I'm doing something to cause this and don't know what.
