Is the turret on a Lee turret press supposed to pop up a bit as the shellholder hits the bottom of a die? I sometimes wonder if mine is the only one that does that. It pops up about 25/1000". I would think that this would an effect on the round being loaded. It seems that the turret would get pushed off kilter as it is pushed unevenly from the front, causing it to pivot slightly, putting uneven pressure on a case being sized or bullet being seated.
