It should be pointed out here that it is possible Frazier made a mistake when he stated the rifle shot 2.5 inches high at 15 yards. As the barrel of a rifle is lower than its scope, and the bullet is travelling in a high arcing parabola on the way to its target, a bullet normally crosses the line of sight from the scope at 10 to 20 yards, meaning the rifle would not shoot high at all at 15 yards. For a rifle to be 2.5 inches high at 15 yards, it would be shooting several feet high at 100 yards.
