Arrow Spine Guide

Arrow spine matching is a baseline step for broadhead stability and repeatable groups.

Inputs That Change Dynamic Spine

• Point weight and insert/outsert mass.
• Arrow length and cut position.
• Draw weight, draw length, and cam aggressiveness.

Practical Workflow

1. Start from a manufacturer spine chart.
2. Account for your actual cut length and point mass.
3. Verify with bare shaft and broadhead testing.

Use the arrow spine calculator to compare options before buying shafts.
