Can you shoot steel case ammo?

Yes. Brass, steel, aluminum and even polymer cased yraining ammo.

Yes, they don't care what you shoot, as long as it is down range, and only when the range is hot😂😂😂 I did a lot of work to my budget AR15, specifically to make it cycle 55grn wolf ammo. It does flawlessly now, but Styx River is wher I go to test it.

Thanks Vito, I got some Tulammo for a great price so it's good to know I can fire away with them.
