the last thing die makers do before they box up the dies

is heat treat them. And in the heat treating sometimes they shrink a bit and sometimes they expand. Normally they don't do this to the extent that they are out of max specs, but sometimes they do. I am sure the sizer die expanded so the brass wasn't sized enough to chamber the round. Schlitz happens.
