I have just started loading 9mm on my Square Deal b and ran into a small problem of the de-primer not pushing the old primer completely out of the casing. Is there a longer pin available? I can't see any way to adjust the de-priming pin, but I know I am giving the machine a full stroke. It only happened to 3 out of 100, and this press is new to me but not a new press.

Thanks
Craig
