OK, I see the pics and that's definitely a pierced primer.
One thing to be aware of, is that a pierced primer sends a little jet of hot gas back into your bolt through that hole, and very often changes the shape of the tip of the firing pin, since that's the first thing those hot gasses encounter. I know guys that had to change their firing pin after a couple pierced primers, because the flame cut tips got sharper and would then pierce everything. That's a 30 second job on an AR, as long as you have a spare firing pin.
Take a look at primers from cases fired when this wasn't a problem, and more recently fired primers, and compare them to make sure that the tip of your firing pin hasn't been changed by those pierced primers.
