Riss, it's a solution to a problem that doesn't exist. As Dave said it doesn't hurt a thing. After uniquetek came out with their "system" I did a little test on my 650. To see just how much the toolhead moves, AND if it does it consistently.
The tool head is at rest on zero on the dial indicator. Of course, I had to remove the powder check head from the powder die to make room for the indicator.
Here it is deflected .013 while under pressure of loading 45 acp shells, all stations working. Point is it deflects the same amount each and every time, with boring regularity. Consistency is what we're after.
How do you know when you lock it down, that you're NOT locking it off angle, instead of tight up against the top of the slot? Without a dial indicator like mine, you won't know!
And I figure if there is zero slop in my RockChucker or any other quality press then there should not be any in the Dillon.
That's funny right there! Grab the ram of a RC or any other single stage press at the top of it's ram travel, pull sideways. You WILL see some slop of the ram in it's bore. No steel bar in a hole can be zero slop without some very precise fitting being done. That costs big bucks, more than we would pay for a reloading press. Again, some movement means it can align with the die better.
