I'd say he's really good and maybe should try a little competition. My experience with the QS was instant, of course 1" groups are not in my bag of brag but I did notice better flight and did experience "tighter" groups at 30, 40, and 50 yds. Tighter meaning smaller than a 1 lb coffee can lid. I quit trying to group 'cause I was doing a lot of refletching. Now I attempt to focus more on "spot shooting". Good hunting to ya.
