I guessed at the .004. On the Lee turret, the "turret" is a seperate disk into which is screwed the dies. The turret disk is maybe 3" round in diameter. It is not part of the press.
The turret is secured to the press in a hole made for it, and it slips in through ample slots and turns a bit to be held from moving up (much) with the ram. It's easy to grab the turret with dies installed and rattle it around (very slightly). The ram applies pressure only to the die in the front of the turret.
So I'm guessing that then the ram comes up under the front edge of the round disk, it's only applying pressure to the front edge and it could possibly or probably tilt the disk. Tilting the disk would move the die out of plumb, if that is happening.
Since I don't know, I ask.
Thanks for all the good input.
