Tuning Broadheads!!

RE: Tuning Broadheads!!
FMARC, first and most important is to bare shaft tune your bow with the arrows you will be using to hunt tipped with target points matching the weight of your broadhead. If your arrows are matched to your draw weight and draw length your broadheads will fly and impact itentical to your field tips. Oh, another important tip, make very sure that your arrow are straight. A good practice is to set aside new arrows just for hunting and keep them just for the hunt. Use other for practice and 3-D shoots.

RE: Tuning Broadheads!!
You paper tune and move your arrow rest position or nockset height to shoot bullet holes,
Now your going to move it again to adjust for broadhead flight, well you just screwed up your paper tuning. Am I correct? They both can't be right. Just wondering about this. It's like you can't have your cake and eat it too.

Forget about the lining up with fletchings thing. It's a bunch of bunk.
I suspect that the four that fly not so good do not spin perfect. I bet there is just a bit of wobble to them or the blades may be slightly bent if you have shot them a number of times..
If they all spin perfect and the blades are straight then the next step would be to move your nocking point down in very very small incraments. I'm not a believer in the thought of not having your broadheads and field points impacting the same spot and simply moving your sight.
8.3% is pretty low IMO for a hunting shaft. You may want to fletch with feathers to get the rear of the arrow lighter to increase the FOC or seriously consider a heavier broadhead as long as it won't make the spine of the arrow to weak.
You might want to post your bow, draw length, draw weight, arrow length, which arrow you are shooting, the arrows spine #, and broadhead weight.
