Thanks Bill. No crimping. .379 slides right in without a bullet. .384 with a bullet and it stops in the exact same place no matter where the bullet is seated. It seems it has to be the chamber neck or case neck. I don?t have a puller, but I?ll seat a slug in an empty case and pull it with pliers to see what happens.
