This reminds me....I've shot that new Ruger ARX ammo, the one that looks like a twisted full metal jacket, supposed to be a decent self defense round, but do not try to use those casings to reload with. There is a false bottom in the case, a gap between the bottom and the primer, like a false floor. I'm not exactly sure what would happen if you tried using it to reload with, but I'm guessing nothing good.
