The 252 scheme consists of shooting 3 dozen arrows at increasing distances using Imperial scoring (9, 7, 5, 3, 1), with 6 sighter arrows first on a 122 cm target face.
When a score of 252 or more is achieved, a quiver badge is awarded for displaying the distance and the legend 252. These are available at 20, 30, 40, 50, 60 80 and 100 yard distances.
If you wish to apply the 252-scheme to shooting styles other than recurve, be sure to consult the following table for equivalent scores across different bow styles.
