Mine shot low brass no problem. I've always stayed away from semi auto shotguns for that reason but folks were saying it'll eat anything and so far their right. Good luck with yours.
The only real drawback is the barrel clamp is plastic and had a tendency to slide forward on the barrel. Having said that Nordic components had a fix but they aren't giving it away. I bought it and have been running thru dbl 00 like it's easy to find.
