Very good chance you have the wrong spine arrows.
A perfectly tuned bow will not shoot the wrong spine with broad heads the same as field points.
Thats what I was thinking. Ive got to where all I do is spin test my broad heads. If they have no wobble, I take them to the field. I do test a broad head before I switch to a different brand, but after that, i just spin test them . Never let me down yet.
