Hi Curtis and Daryl,
I used to compete in biathlon (skiing and shooting) and was coached by instructors with the US Army National Guard biathlon team. More important, I was taught to shoot shotguns, pistols, and rifles by my brother John, one of the best shooters ever produced by the US. John shot the Berdan's sharpshooter qualifier sponsored by the NSSA in 1991. The test is to shoot 10 shots with a standard Civil War era rifled musket and military sights offhand at 100 yards. The deviation from center for each shot is measured and totaled, and cannot exceed 50" to qualify. John's total deviation, shot with a Parker Hale 3-band Enfield musket was 14". Nine of his shots almost touched in the center with 1 flier 3" out. That score will probably never be exceeded. John passed away last May.
