Make broadheads and field points hit together — the final exam your setup must pass before opening day.
Make broadheads and field points hit together — the final exam your setup must pass before opening day. Follow the steps in order — each one builds on the last.
Step 1: Start with a tuned bow
Broadhead tuning refines a paper-tuned bow; it cannot rescue an untuned one.
Step 2: Shoot both at 30 yards
Three field points, then three broadheads (same weight) at a fresh target face. Mark each group.
Step 3: Move the rest toward the field points
Broadheads left of field points: move the rest right 1/64″, and vice versa. Vertical gaps: adjust nocking point.
Step 4: Repeat until they merge
Two or three iterations usually converge the groups completely.
Step 5: Confirm at your max range
Groups that touch at 30 must still agree at 50 — broadhead planing grows with distance.
Step 6: Re-sharpen or replace blades
Practice dulls blades; hunt with fresh edges and spin-test every assembled arrow.
Why Broadhead Tuning Is Non-Negotiable
Field points and broadheads do not fly the same way. A broadhead has blades up front that act like little wings, steering the nose of the arrow and magnifying any flaw in your tune, spine, or rest contact that field points quietly forgive. You can shoot perfect groups with field points all summer and still watch your first broadhead plane a foot off target on opening day. Broadhead tuning closes that gap before it costs you an animal.
Think of it as the final exam your whole setup has to pass. If your broadheads and field points hit the same spot at distance, every upstream step, from cam timing to center shot to arrow spine, is confirmed correct. If they do not, broadhead tuning tells you exactly how much error is still hiding in the system.
What You Will Need
- Two or three identical broadheads matched to your hunting arrow weight
- Several field points of the exact same grain weight as your broadheads
- A broadhead-rated target that will not destroy the blades
- An Allen wrench for micro rest adjustments and a tuned, paper-checked bow to start
Common Mistakes to Avoid
- Tuning with dull or damaged broadheads that fly erratically no matter what you do
- Using broadheads and field points of different weights, which guarantees different impacts
- Starting before the bow is paper tuned, so you fight problems that are not broadhead related
- Moving the rest in large jumps instead of small, repeatable steps toward the field points
- Tuning at twenty yards only, when the gap really shows itself at thirty or forty
Pro Tips for Broadhead Tuning
- Shoot field points and broadheads at the same dot from thirty yards and move the rest toward the field points
- Move the rest in tiny increments, then confirm before moving again
- If you cannot close the gap, suspect arrow spine or a clearance issue, not just the rest
- Mechanical heads mask tune errors, but a broadhead-tuned bow still groups everything tighter
- Re-sharpen or swap to fresh blades before the hunt, since you tuned with practice heads
Final Word
Broadhead tuning is the last and most important step before season, because it validates everything else. When your broadheads stack into the same group as your field points at hunting distance, you can trust your sight tape and your setup completely. Do this every year, and after any change to arrows, rest, or string, so opening day is a formality, not a gamble.
Frequently Asked Questions
Why do broadheads hit differently than field points?
Fixed blades steer the front of the arrow like small wings, amplifying any tune or spine error that field points hide.
Do mechanical broadheads need tuning too?
They mask tune issues better, but a broadhead-tuned bow groups both styles tighter, and you want that margin on a real animal.
How do I close the gap between broadheads and field points?
Move your rest a small amount toward the field-point group, re-shoot, and repeat until the two impacts merge.
What if I cannot get them to hit together?
A stubborn gap usually points to arrow spine, fletching clearance, or a deeper tune issue rather than just rest position.
How far out should I broadhead tune?
Tune at thirty to forty yards, because small errors that are invisible at twenty become obvious and fixable at distance.
