I went thru all that with the shot bushings several yrs ago. I never had one of any brand throw anything but light. To me there is no mystery there - I never load chilled shot (almost pure lead) and all of the hard shot is hardened with something lighter than lead. Get a bag of something more like pure lead and the drop by volume will likely be closer to what is marked. TabA/SlotB
I opened up a few extra bushings to the real weight but that unfortunately made no detectable difference in my shooting performance.

just a thot
