That sometimes happens without the operator's knowing, especially if they're not paying attention to each shell as it cycles through the press. If it was done on purpose, it was done by somebody who didn't have a clue about that press. They would have been better off with a Lee Load-All.
Crimp too deep is a function of final crimp. Shot being
exposed could indicate need to adjust start crimp. Adjusting
start crimp lower will close the hole. Would adjust final
crimp to depth desired and then make final adjustments with
<I><blockquote>"Loosen the jamb nut on the top and turn the screw CCW. Go slow, about one turn or less each time. This will adjust the crimp depth."</blockquote></I>Once you get the crimp depth where you want it, if the hole is still there (which it probably will be) lower the crimp starter 1/16" by loosening the Allen head set screw in the back of the top crosshead. (I put a piece of masking tape around the crimp starter post to use as a reference for how far I'm moved the post.) If lowering the crimp starter closes the hole but makes the crimp too deep, raise the final crimp assembly a bit more and try again.
The lower jamb nut that controls the end taper of the hull can complicate matters if it's used to control the closing of the crimp. It's job is to adjust the final crimp spring pressure and control the taper of the end of hulls that must feed into semi-autos. It affects some hulls more than others.
Since many people ignore it, it is usually still at the factory setting even after the press has been used for years. Leave it alone and see what you can accomplish with the crimp starter and the crimp depth adjustments only. You're going to end up juggling the two adjustments until you get the crimp you want.
I made my adjustments using fired hulls with the used primers still installed (remove the depriming punch from the press first). I used sawdust in place of powder and measured it in a cut down bullet case. After the hulls were crimped I cut them open, salvaged the wad and shot and made more. Let the wads relax for a day or two and they'll be good as new.
