Reloading Short 10 help

[J.B. Books]

You have a hole in the center of the crimp of all three loaded shells. I would try two things, adjust the cam to help get a better crimp and close the hole (see attached link). You can also lower the crimp starter with washer between it and the plate that holds it. That will make a more well defined pre crimp prior to closing it.

Thanks guys. I will try both as soon as I can find some more hulls.
These are all once fired hulls.
