Imagine the situation...
One of your shooting partners...let's call him "Cholly" takes a shot and plates the target.
He even considers getting it checked as he can't see a new pellet mark on the plate.
I ask him "was it the diamond below the stander ?"
"No" he replies, "it's the rabbit in the dark tunnel"
Then your other shooting partner...let's call him "Vonty" shoots the target and it falls. Pulls the string and it goes to the diamond below the stander.
Oh how I laughed....double donut on one target...and it let's me take the win between us !!
Schoolboy error....PULL THE STRING.....
