I have my die adjusted exactly as I should. It just clears the press' plate on the full down stroke.
Your right, there's no way to get the round any further into the die without risking it hitting the press. That would be bad for the Carbide.
Not a huge problem, I was just concerned about the slight bulge I felt then was able to see and eventually measure.
I'm sure they will work very well in the wheel gun.
