You guys who shoot 2-3" groups at twenty yards are the best in the world! Congratulations!
The 5-ring on a "blue-face" target is 3 and 1/8 inches in diameter. An NFAA indoor round is shot at 20 yards, using a blue-face. With all 60 of your shots in the 5-ring, you're shooting a perfect 300! You will win every tournament in the world by a significant margin.
Of course, if your group isn't in the 5-ring, a group isn't of much value, is it?
