Dave, at 100 yards, that is superb accuracy for a pistol caliber carbine. And, if he can repeat it with that gun, it is extraordinary. I shot mine a lot with a 2x7 Nikon, lots of hand loads and a couple of factory loads, and 1.5 to 2" was about the best I could do. Don't get me wrong, I am very satisfied with that accuracy. If my gun will shoot smaller groups than that, my shooting skills must be the limiting factor. :oops:
