Definitely a 125 grain .357 round. Everything else was hitting the paper like it should. It was the only one I had a problem with.

I was eye-balling all of them after weighing each charge, with a flashlight. But, again, anything is possible.

I was using a Lee Perfect Powder Measure. I made sure I was deliberately working it up and down and tapping on it to get excess flakes out as well for each charge. I'm a tiny bit concerned because I know I measured every charge.
If you are confident of powder in every charge, then I will say deactivated powder. Moisture or oil residual in the case that let teh primer pop the bullet out but not burn the powder.
