i was throwing .45acp 200 grain from a mihec four hole mould with pins yesterday.
didn't catch it until i started resizing them, but a number were to large to fit in the .452 sizer die.
Got to looking at the mould today, and it wasn't fully closing you could rock it front and back and there was movement.
took the pins out and it was flush.
One of two things, either the pin was just a little too large, or had worked loose, meaning my fault i should have checked they were tight.
I think this is more the case, as of about 300 bullets cast, 20 or 30 were this way which probable meant the pin had loosened up.
One question, is anyone lubricating the pin holes in the mould?
