Cloverleaf looks to be possible with that at 50 yards, was just curious, I do not see 6 on the 50 yard target, is it out of frame or was this taken before shot 6?
I wonder how much curve happens to the round ball, throwing a ball or shooting a ball has some really unpredictable movement, would be fine close up but the further away the curve can do weird things. I guess if there is not much spin imparted on the ball by the rifling this type of effect may occur.
