Thanks Bart. I have one reloading book that says the same thing, not to put too much stock in reading primers as signs of overpressure and then one reloading book that says to look at your primers as an indication of when overpressurization. Look at this one though and it looks very bad to me...First picture is a primed round, second one is a fired round with same load as the others but the headspace was out just a little more than the OP pics. Could that have made the difference?
If you heard the bang,
You weren't the target.
