I didn't have much time anyway, but I wanted to run some Speer Gold Dots through the ATI -- just to see how they fed and felt. In 12 rounds, I had one feed jam. Compare that to the, oh, I dunno... 500 or so rounds of Blazer Brass that I've run -- without a single feed jam. All shots at 21 feet on some used cardboard: I still feel like something isn't quite right with the relationship between the sight picture, and what gets thrown down. Horizontal axis, it's close enough for my satisfaction. Vertically, it's inconsistent, and I don't know why. Id love to get some other hands on it to see if maybe it's just me.
