I am lucky that my field points hit within minute space from broadheads. My thought is your bow, like some guns, handles one shell better, mine handles one type of broadhead. I use Crimson Talons and hit where the field points hit, yet I used another type from Spintite and it did the same, like right and low. So I switched back to the Talons and was on again. So think you might want to try another broadhead!
