All of them the gas check shanks are too big. You cant get a reply or any customer service. He knows about the problem as I am not the only one and he will not remedy the problem. There is only one fix and that is to remake the molds so I am sure that is the issue. Top punches are not a big deal but they are incorrect. I just want everyone to know what happens if there is a problem. I have Accurate molds now and have moved on. They are far superior in every way including the man who makes them. He is a man of his word.
