I've been shooting for 9 months.
Maybe I am
using the wrong pin!! I didn't even think of that.
Whenever it happens, it is always dead on left and right, and 1 ft high (never left, never right, never low and always 1ft from center). When I'm at the 3D range - I use the bottom pin and move the wheel to the exact yardage (Hog Father). When I'm shooting at home I use the top pin. My top pin is 20, middle pin 30 and bottom pin 40. I bet that pin gap from 20 to 40 (at 20 yards) is 1ft exactly. I'll check this tonight.
It is definitely a different arrow each time (they shatter when they hit the bricks).
