I have no idea what you're talking about...

"Slop", "tolerances", how is that going to degrade in a progressive press?

The dies are the same, used the exact same way....

Specifics to back your argument?
To my mind, "slop" is pejorative and therefore, argumentative. Forgive me, please, if I am wrong. Tolerances and "play" are less so. Most Single stage presses are cast in one piece and have no play and (arguably) a tolerance of zero, by definition. Progressives and turrets are necessarily an assembly of parts, some of which move. They must have clearances to move and those clearances/tolerances can "stack". "Tolerance Stacking" is a term of art in machinists' language. Look it up.

And.. do you OWN a progressive press??

Seems to be a lot of armchair quarterbacking here...
Maybe, maybe not. Did you take a look at his posting history to see what kind of experience he claims?

Be nice, please. We are trying to give advice to a newcomer. Invective is not useful in that regard, is it?
