Default Broad head tuning?

I have been shooting all summer with field points and my field points on my hunting arrows are accurate. But practicing with my mechanical broadheads with the same arrows are about 3-4" low. Can I tune them in by adjusting my pins or do you reccomend changing something else? I am shooting:

piledriver arrow 350 spine @ 10.32 g/ inch= 283.8g arrow
100 grain NAP killzone
Diamond Outlaw @ 65 lbs
28" Draw length

Thank You

Paper tune your bow. Something is out of whack.

According to your total grains, your arrow is 34.5 inches long. Is that correct?? You may need a different spine arrow for your setup.

Are you shooting with a practice killzone broadhead? if you are using field points and then switching to your killzone broadhead it may just fly a little different. IF the broadhead is consistent just in a different location than your field tips I would suspect that is what is going on. Hope this helps

Your bow is out of tune or your spine is incorrect. A perfectly tuned bow will shoot broad heads and field tips (practice tips) pretty much the same.

spine issues tend to show left/right BH movement.

If your BH is slightly low, raise your rest about 1/16th of an inch and try again. Repeat until you have them together.

This ^^^

Spine issues are usually left-right. Bump your rest up slowly until your groups come together!
