Anything is possible with the primer. Seating depth is supposed to make a difference with ignition of the powder charge (I don't know for sure). So if the primer is only partially seated in the primer pocket (only one side of the primer seated completely), it's possible the flame won't go through the flashhole consistently. That would affect the ignition of the powder charge which would have a large effect on accuracy.
Also possible the priming pellet compound is partially crushed which might affect the ignition of the primer, causing a change in the ignition of the powder charge. Might not make a difference for blasting ammo, but for precision type shooting, such as load development, etc I would not include the pictured cartridges in the ones I am shooting for extreme accuracy tests.
I gotcha. I guess I was thinking from purely a pressure perspective. From an ignition perspective, I could see that.
OP- Will you let us know the result? If you decide to send them, and if you do, how they perform?
