It could be because it is off center. It also looks as though the firing pin might be a tad sharp and tried to pierce the primer instead of smashing it. I've always bee told that that a primer may fail to go off if struck off center, simply because the high part of the anvil is in the center, and if the anvil in the primer isn't struck, the mix won't go off.

The strikes on these cartridges completely miss the center.
