Someone said this in another thread and it made sense to me. Applies to this as well. "With the backorders that manufactures are dealing with, most are working non stop just to put products out. In these situations you almost always see QC fall by the wayside."
I'd definitely ask them to replace the box. If you have more ammo that you got from that same lot I'd ask them to replace those as well. You never know, they could be double charged or something else. That's a pretty big liability that they're dealing with if they're letting ammo out like that. I know it's uncommon but two rounds from the same box seems a little iffy to me.
On the other hand hopefully they're sending that crap in the billions and millions orders from homeland!
If you've got one foot in yesterday, and the other in tomorrow, than you're pissing on today.
