What Factors Should Influence My Arrow Length Choice?

Factors Affecting Cam Timing

When selecting arrow length, it’s essential to consider cam timing on your compound bow. Most compound bows have a recommended arrow length range based on the manufacturer’s suggested cam timing. For example, if you’re using a bow with 75% let-off and a cam timing of 6.5 inches, you’ll want to choose an arrow length that’s within 1-2 inches of this setting. This will ensure that the arrow is aligned properly with the bow’s cam system, minimizing any potential issues with accuracy and consistency.

Measuring Your Draw Length and Arm Length

To determine the right arrow length for your bow, you’ll need to measure your draw length and arm length. A good rule of thumb is to choose an arrow that’s between 1/8 and 1/4 inch longer than your draw length. This will give you enough clearance to ensure proper arrow alignment and prevent any issues with torque or arrow wobble. Additionally, consider your arm length and the distance between the arrow rest and your bow’s riser. You want to make sure that the arrow is aligned properly and that the rest is not too close or too far away from your bow’s riser.

Using the Walk-Back Method for Tuning

The walk-back method is a simple and effective way to tune your bow and find the right arrow length. Start by setting your arrow rest to the manufacturer’s recommended setting and then shoot a group of arrows at 20 yards. Next, move the rest back 1/8 inch and shoot another group of arrows. If the group moves to the left, move the rest back another 1/8 inch and shoot again. Continue this process until you find the correct arrow length that produces a tight group. This method can help you find the optimal arrow length for your bow and ensure a consistent and accurate shot.
