I primed each case with a Lee Hand Priming tool, that had always given me good results with more than flush seating, and I usually check each round with my finger for flush-ness, but??? There's always the possibility that a bad one slipped through. The moral to the story is, if in doubt, recheck the whole lot again.
I have recently noticed that one of my 2 Lee Priming Tools (the one set up for large diameter primers) is not consistently seating primers deep enough. I have to fully seat these primers using the priming arm of my press. Doing this, primers are always seated below flush.
