Wow, I sure don't know how it could fire and not be dented! Even the few misfires I have had (with my KRB) have had a slight dent in them, but not as deep as normal. The only guess I could venture is that the primer is sealed so tight against blowback that the pressure pushes the dent in the primer back out??
