XM193 is loaded in Lake City brass, I know it's ran by Federal but the LC brass is totally different than Federal's own.

On another note, I just ran the last 2 mags of XM193 I had today. I've shot quite a bit of this stuff without issue but have decided to just roll my own MK262 clone load for all my shooting. It's easier having 4 AR's zeroed with the same ammo for all purposes.
