  Do you have a picture?   Right on the "shoulder" where the straight neck meets the angled part of the case? 

  Could be overlubing the cases, that can cause ripples/bulges in the brass.  Ask me how I know  :cool

What dies are you using? Is it crushing brass at the sizing step or the bullet seating?

Hornady 223 dies, at the seating step.  Redid setup and started again worked fin for a 45 case run.  Now time to prime the rest of the cases and run cases out to see it holds.

If you are crushing the necks at the seating die then chances are you have the die body screwed down too far as it's over-crimping the case while it's seating and crumpling the necks.  If that's the case this is how to set up the seating die.  Have a empty sized case in the shell holder and the seating die unscrewed about 3/4 way out.  Put the ram all the way up and then screw down the die until you feel the crimper contact the case mouth and then back out about 2 turns and lock down.  Now just adjust the bullet seater to the proper depth. 

With this setup you are seating w/o a crimp and IMO the crimps in the seater dies don't work nearly as well as a separate crimp die.  I use the Lee Factory Crimp Die as it uses a collet to crimp and is activated by the case shoulder instead of the neck itself and that way no matter if your cases are a little longer or shorter you will get the same crimp all the time.  Uniformity is the key to accurate reloads and a consistent crimp is just as important as a consistent powder charge.

what I was thinking need to get a 3 die set where this set is a 2 die set.  Guess I will see what a set runs.

You already have the two die set.  Just get the separate FCD.  Cheaper in the long run.

Mattitude nailed your issue.   

Back that die body off until no crimp is being applied, and then crank just the seating stem down until a bullet is seated to proper depth. 

Now back the seating stem clear out, and slowly crank the die body down until you have a light crimp.  Lock the die in place at this point.

With the die body locked at the right depth for your crimp, put your test round in the shell holder and raise the ram.  With the ram up, crank the seating stem back down until it hits the bullet. Lower the ram and add 1/16-1/8 turn deeper.  Lock the stem in place.

Now try seating and crimping again on your newly adjusted die.

Or, get a Lee factory crimp die and seat in one step and crimp in the next.

Right now I am holding off on 6.56 rounds reloading,  will check at the gun show in Lima for crimp die.  Have ran about 100 380's with no issues.
