I've discovered that a motivated Marine can indeed almost get a .452 boolit to go through a NOE .430 sizing bushing. I was sizing some .44 boolits and a .45 boolit slipped into the mix. Since the .44 boolits were a bit oversized it was taking a bit of effort to get them through the sizer. So when the .45 boolit got there I didn't think anything about it. Leaned into my Hornady SS press a bit too hard. Had to pound the boolit out, it didn't survive. Had to pound the bushing out of the die body, it didn't survive either. It will no longer fit in the die body. The good news is the die body is still good.
