Primer Blow Out with NO Over Pressure Signs?

You've been doing it for longer than I have, but is there a possibility you got coal too long and they're engaging the rifling when you fired?

Thanks for the reply, I went to the IMR Load Data website to verify, but 2.800" is a standard length for 308Win ammo.

And while I haven't measured my rifle's distance from bolt face to rifling (tried, the result didn't make sense as I recall), I shot 20rds of Federal Gold Medal Match through my rifle when I was sighting in the scope and they were all exactly 2.800" +/- 0.0005" (not that I could measure that, but it was less than 0.001" variance)
