I've also found, and I can't find the post now, but someone else also pointed it out a while back, some 9mm cases with what looks like they have a portion of a smaller caliber case shoved into them. It really isn't another case but it does really reduce the internal capacity compared to other brands.
I load a LOT of ammo using Bullseye and would not probably have been happy using one of those with a couple of the higher pressure loads. Not that I am over book by any stretch, but considering how temperamental a 9mm is on seating depth verses pressure spikes with some of the faster powders, or longer bullets, I don't want to take those sort of chances.
