After looking at the photo again I'd feel even more confident in assuming that you didn't get decent ignition for that round, probably because of a bad primer. I didn't notice any unburned powder when I squibbed the one in my 442 so I assumed that I truly missed a powder throw when dealing with brass catching during one of the stages. The bullet still managed to make its way all the way to the crown of the barrel...
Ironically, the only time I ever had an ammo-related issue with 9mm was with factory ammo...with the last box of factory ammo I purchased actually. I had several powder-puff rounds go through my gun resulting in an FTF and, after stopping to inspect the barrel I noticed unburned powder all over the place. That came from the standard 100-round pack of 115gr WWB that used to cost $9.97 at Walmart back in the good ol' days.
