"With that as a design base, I can tell you that the TPR is capable of extreme accuracy," says Mastison. "Generally these guns are built to shoot sub MOA, with the ability to shoot ¾ to ½" groups at 100 yards. With a barrel length of 20" and a 1x9 rate of twist, I would run 55 grain SMK match ammo through it. With good optics and a clean trigger, a decent shooter can get good and consistent hits at 600 yards. If you employ a good spotter /shooter team? This rifle could be capable of 800-plus yard hits, if weather cooperates."
