You may be right about magazine curvature and feeding. I have no experience with that. But, I definitely have experience watching several different shooters on several different occasions trying to get stuck cases out of their AR chambers, and they were universally shooting steel cased ammo. I've never seen a brass case get stuck in an AR chamber. I can only speak from my experience.cajunautoxer wrote:Brass vs steel isn't the issue. Some people speculate it's the curvature(sp) of the mag
Now if we were discussing FTE in ARs that people shoot brass and steel then yes brass vs steel is an issue
