I've got one and shot it in mine a couple of years ago. The only serious patterning I did with it was with Nitro's, and it did pretty well. Not the high numbers that some folks were showing with the tighter constrictions and the Nitros, but a nice evenly distributed pattern with some wiggle room, which was what I was looking for. I'd have to look at my notes, but I think it averaged around 180 in a 10" circle at 40 yards with the Nitro Straight 7's.
