Did you pull the bullet to make sure it had powder in the case?
Wouldnt primer ignition still make a bang?
No. I did it once in a 308. Bullet never left the case.
I've never pulled the trigger on a primed round with no powder. The primer doesn't make even an audible pop... like a cap going off?
Not that i noticed.
There really can't be a pop if the bullet doesn't move.
It didn't. I had no idea what happened until I pulled the bullet.
That was my wakeup call to always, always, check every single round
in the block for powder level against it's neighbors.
