Just got back from dinner. Would've posted earlier.

The seating depth looks fin in your pic.
I knew seating the bullet deeper would cause a spike in pressure. Honestly not sure why I even said anything about it.

I am surprised it is even going into battery. When it comes to reloading you should not be so cheap that you are using the wrong dies. A set of Lee 9mm dies will cost less than 2 boxes of factory ammo. They are much cheaper than a new gun or a trip to the emergency room.
Thanks for the advice. For what its worth, I'm only using the .357/.38 for priming.
Like I said, I am new to reloading. What kinds of crimps are there, and what do you mean by a roll crimp?
You're spot on with the lead shaving off thing, but I believe that is actually happening in my Hornady bullet seating die (it also crimps in the same step), which is actually for 9mm. I assumed this was just a side-effect of using non-jacketed bullets.
I have been meaning to buy a new set of dies anyway, as I honestly don't really like the Hornady set. Previously, I had an issue with consistency in seating depths. I believe I have eliminated that problem, but it left a bad taste in my mouth.
So Rick, you're pretty convinced its an issue with the wrong crimp? You don't think the round isn't seating far enough into the bbl?
