In a controlled drill, which metric is used to express group size as a single value?

• A. Diameter of the Smallest Circle Containing All Shots
• B. Total Number of Shots
• C. Average Recoil Path Length
• D. Time to Complete Drill

Answer: (A)

Grouping is quantified with a single value that reflects how tightly shots cluster on the target. The best single-number metric for this is the diameter of the smallest circle that contains every shot. You plot all impacts, determine the smallest circle that covers them all, and measure that circle’s diameter. A smaller diameter means tighter grouping and better precision at the given distance, which is exactly what this drill aims to assess. The other options don’t capture dispersion in a single value: total number of shots tells you how many were fired, not where they landed; average recoil path length isn’t about shot placement on the target; and time to complete the drill measures speed, not accuracy.
