Good thinking to check your headspace with the tape method.

If you flatten out a cast bullet just enough and then pound it into the chamber just enough, you can get an impression of the step at the end of the chamber. It is supposed to be real close to a squared off step. Make sure it is not more of a bevel and is not a "double step". Having the wrong step profile could lead to an infrequent and random problem.
