I would think if youre paper tuned you would be broadhead tuned.... I have never had a problem if my bow was papertuned well. I don't really understand broadhead tuning though. just my .02
If your bow is papertuned and you're shooting "bullets" through paper, you shouldn't have to do anything else.
If you have cam lean, you can broadhead tune and still have a tear in paper. Or if you torque the bow.
So, this also means you can paper tune and broadheads may not impact with field points. Arrow spine can also mess up your results.
