Posi unit exploded today. Punched it from a 30 roll and that was it. I got it home, pulled the cover off, and pieces were laying all over the bottom of the pumpkin. I knew it was going to happen sooner or later. Now I have a good excuse to tell the wifey I need to pick up an Eaton or Auburn unit and drop in a set of 4.30 or 4.56s.
