If your seating die is still set up in the press go and run a scrap case with no primer powder or bullet in it up into the die until the handle stops. If the neck comes out munched and squashed you have your answer.

Most seating die instructions suggest to put an empty case in the shellholder and raise the press handle. Then back the seating adjustment right off and wind the die body down into the press. At some point the crimping function will contact the case mouth - at this point back the die out one full rotation and nip the lockring. Now you can go ahead and adjust your projectile seating depth.

Did setup up the die for non crimping but this makes sense to me. I may have missed the critical step of not winding out the die enough.
Will run through this again. Thank you.
