FRED ZEGLIN: If he did not mention the feeler gage he had limited shop skills. If the shell holder does not make it up to the bottom of the die the case did not get sized. If the reloader wants to know if the case had more resistance to sizing than the press/lube could overcome the reloader can measure the gap between the top of the shell holder and bottom of the die to determine the amount of the case that did not get sized.By the way he doesn’t mention feeler gauges and all the extra comments you offer. Your comments are all bragging on how much you know and how stupid all other reloaders are and how superior your equipment is compared to other reloaders.
And then if the shell holder does not make it to the bottom of the die an advanced reloader can remove the die with the protruding case to measure the case head protrusion. If the case is returned to minimum length the case had will be protruding .125" because the deck height of the shell holder is .125". I doubt Old Fred would have been one of my fans.
