10 gauge reload Issues

[Keith Doty]

Suspicion here is the start crimp isn't getting a deep enough start and some of the hull is "outside" of the center flat of the final crimp and hooking the edge of the shell mouth. Has your adjustment on start crimp slipped or moved?

You are correct Keith, after doing a little more digging, I found that Mec says the start crimp should close the shell far enough that a primer will not fit in. My start crimp had worked loose and after some adjustments, I loaded 30 that looked like this.
Thanks for all the advice,
Stan
