    Isn't Hornady steel case Zinc coated? I would have thought Zinc to have less friction than brass and therefore feed better.

    No. It looks like a laqueer coating.

    Gotcha. So this is really a conundrum about why cheap ammo wont work in an expensive magazine

    I have fed mine only XM193 and not had any issues.

    I bet it's the load. I wonder if the guys having problems are NOT shooting through a can... A suppressor might help make up for the weaker load on that ammo.

    I think that it's the change in spring tension/speed during the transition of followers inside the mag. I have puns that the more I use them the smoother they get. I don't think I would bet my life on them at this point.

    According to the specs located here:
    http://www.surefire.com/mag5-100.html

    the mag is heavier when it is empty compared to when it is full. That is incredible!
