Quick Answer
To choose the right spine for wooden arrows, consider your arrow weight, bow speed, and personal shooting style, then select a spine rating that matches your draw weight and arrow length.
Selecting the Right Spine Rating
When choosing a spine rating for wooden arrows, the traditional method is to use the bow’s draw weight and arrow length to determine the correct spine. A general rule of thumb is to use the following spine rating chart: 500-600 grain arrows for low draw weights (40-60 lbs), 600-700 grain arrows for medium draw weights (60-80 lbs), and 700-800 grain arrows for high draw weights (80-100 lbs).
Understanding Arrow Weight and Length
Arrow weight is crucial in determining the correct spine rating. A heavier arrow requires a stiffer spine to prevent it from deflecting or wobbling in flight, while a lighter arrow can use a softer spine. Arrow length also plays a role, as longer arrows require a stiffer spine to maintain stability and consistency. A good starting point is to use an arrow that is 28-30 inches long, with a weight of 500-600 grains.
Measuring Your Draw Weight
To determine your draw weight, use a draw weight scale or a spring scale attached to your bow. Ensure the scale is securely attached and measures the weight at the point of arrow release. This will give you an accurate reading of your bow’s draw weight, which you can then use to select the correct spine rating for your arrows.
