I like to shoot a 5, 10, 15, 20, 25 foot course that shoots up 50 rounds.
You fire 10 shots at a specified circle of a certain diameter (I'm still using 6 inches).
You score 1 point for each hit at 5 ft, 2 points for each hit at 10 ft, 3 points for each hit at 15 ft, 4 points for each hit at 20 ft, . . . and 5 points for each hit at 25 ft.
You cannot move to the next stage until you have shot a full string of 10 with no misses. For example: first string, 10 shots, 10 hits = 10 points / second string 10 shots, 8 hits = 16 points, and you have to shoot stage 2 over at 10 feet. Obviously in this scenario, you will not shoot stage 5, because you shot stage 2 twice.
I save this exercise for last, . . . and go inside with this score in my head, . . . comparing it to the one prior to.
It's fun.
May God bless,
Dwight
