if you punch poly, they stack up for about 10, then they have to be removed
when I punch paper, and i use erasable bond, folded over to punch 4-6 at a time
you must remove them after 3-4 punches or the seal of the paper on the punch acts
like a piston and shoots the paper punchouts all over the floor.
all you have to do is pay attention. I have 3 of Fred's punches, .38, .40, .45
all have been very servicable, bought them from Fred personally.
