I've been using steel cases ammo interchangeably in all my firearms. It fires and functions just like the cases made from other materials. I shoot Wolf steel cased ammo exclusively in my AR. 3 cases worth since I got the rifle. It does shoot dirty which is no problem as I keep my firearms cleaned after each range outing. The stuff just works well for me. It's just another example of actually using the product in question as opposed to drawing my conclusions solely from word of mouth.
Any sufficiently advanced technology is indistinguishable from magic.
