Setting the draw weight on a compound bow is a crucial step in ensuring accuracy, consistency, and overall shooting performance. Unlike traditional bows, where the draw weight is determined by the bow’s physical design, compound bows allow for precise adjustments to suit individual archers’ needs and preferences. Whether you’re a seasoned archer or just starting out, understanding how to set the draw weight is essential for a safe and enjoyable shooting experience.
Before adjusting the draw weight, it’s important to consider factors such as your physical strength, shooting style, and intended use for the bow. A properly set draw weight should allow you to draw the bow smoothly and comfortably, without straining your muscles or compromising form. Begin by setting the draw weight at a manageable level, typically 10-15 pounds less than your estimated maximum draw weight, and gradually increase it as you gain strength and proficiency. Remember, the goal is to achieve a draw weight that supports your shooting objectives without causing discomfort or compromising accuracy.
To adjust the draw weight, locate the limb bolts or adjustment screws on the limbs of the bow. These are typically found at the base or top of the limbs and can be turned using a bow press or an Allen key. Turning the bolts clockwise will increase the draw weight, while turning them counterclockwise will decrease it. Make small, incremental adjustments and double-check the draw weight using a bow scale to ensure accuracy. Once the desired draw weight is achieved, tighten the bolts securely to prevent any unintended adjustments. It’s always advisable to seek guidance from an experienced archer or bow technician if you encounter any difficulties during the adjustment process.
Determining Your Ideal Draw Weight
Selecting the optimal draw weight for your compound bow is crucial for accuracy, comfort, and safety. The appropriate draw weight varies based on your physical strength, body size, and bow’s capabilities. Here are some factors to consider when determining your ideal draw weight:
1. Physical Strength and Fitness
Your physical strength and fitness level significantly influence your draw weight selection. Beginners may start with a lower draw weight, typically between 30 and 40 pounds. As you gain strength and experience, you can gradually increase the draw weight to enhance arrow velocity and penetration.
2. Bow Capabilities
The manufacturer’s specifications determine the maximum draw weight your bow can handle safely. Exceeding this limit can damage the bow or cause injury. Always refer to the bow’s owner’s manual for its maximum draw weight rating.
3. Body Size and Draw Length
Your body size and draw length (the distance from the nocking point to the bottom of the grip when fully drawn) influence your ideal draw weight. Individuals with longer draw lengths typically require higher draw weights to achieve the same arrow velocity. Consult with a qualified archery expert for guidance on determining the appropriate draw weight for your physique.
4. Intended Use
Consider the intended use of your compound bow when selecting the draw weight. If you plan to target shoot at shorter distances, a lower draw weight may be sufficient. However, for hunting larger game or shooting at longer ranges, a higher draw weight is generally preferred.
The following table provides approximate draw weight recommendations based on physical strength and body size:
| Physical Strength | Approximate Draw Weight (pounds) |
|---|---|
| Beginner | 30-40 |
| Intermediate | 45-55 |
| Advanced | 55-65 |
Measuring Your Draw Length
Determining your correct draw length is essential for both accuracy and comfort when using a compound bow. Follow these steps to ensure a precise measurement:
1. Position Your Feet: Stand with your feet shoulder-width apart and perpendicular to your target.
2. Find Your Anchor Point: Place the bowstring on the tip of your nose and draw it back until the string touches the corner of your mouth. This is your anchor point.
3. Measure Your Wingspan: Stand with your arms extended parallel to the ground. Have someone measure the distance between the tips of your middle fingers.
4. Calculate Your Draw Length: Subtract 15 inches from your wingspan measurement. This value is your approximate draw length.
5. Fine-Tune Your Measurement: Once you have a starting point, make adjustments until you find the draw length that feels most comfortable and accurate. Increase the draw length to reduce finger pinch and decrease it to eliminate excessive string slap.

| Module Setting | Draw Length (Inches) |
|---|---|
| A | 26 |
| B | 26.5 |
| C | 27 |
| D | 27.5 |
| E | 28 |
Adjusting the Limb Bolts
The limb bolts are located at the top and bottom of each limb and are used to adjust the draw weight. To increase the draw weight, turn the bolts clockwise. To decrease the draw weight, turn the bolts counterclockwise. The amount of adjustment required will vary depending on the bow and the desired draw weight.
Locating the Limb Bolts
The limb bolts are typically located on the back of the bow, near the top and bottom of the limbs. They are usually hex-shaped and may have a locking mechanism to prevent them from loosening inadvertently. Some bows may have a single limb bolt per limb, while others may have two or more.
Adjusting the Limb Bolts
To adjust the limb bolts, you will need an Allen wrench or hex key of the appropriate size. Insert the wrench into the bolt and turn it in the desired direction. Be sure to tighten the bolts evenly to ensure that the draw weight is balanced on both sides of the bow.
When adjusting the limb bolts, it is important to make small adjustments and then recheck the draw weight. This will help to prevent overadjusting and damaging the bow.
| Draw Weight | Limb Bolt Adjustment |
|---|---|
| Increase | Turn clockwise |
| Decrease | Turn counterclockwise |
Checking the Draw Weight
Checking the draw weight of your compound bow is a crucial step that ensures safe and effective use. Follow these steps to accurately determine the draw weight:
1. Adjust Limbs
Adjust the limbs by rotating them until the limb bolts are flush with the bow riser and the limb markings align correctly.
2. Set the Limb Bolts
Tighten or loosen the limb bolts evenly to achieve the desired draw weight. Refer to the bow manufacturer’s specifications for the appropriate draw weight range.
3. Install Bowstring
Attach the bowstring to the limbs and hook it onto the cams. Ensure that the string is in the proper track on the cams.
4. Use a Bow Scale
Hang the compound bow vertically from a bow scale. The bow scale should measure the force required to draw the bow to a designated draw length. Typically, a 28-inch draw length is used as the standard measurement. Read the scale to obtain the draw weight in pounds.
The following table provides a guide to approximate draw weight measurements based on the distance the string is pulled:
| Draw Length (in) | Approximate Draw Weight (lbs) |
|---|---|
| 26 | 60-70 |
| 27 | 65-75 |
| 28 | 70-80 |
Fine-Tuning the Draw Feel
Once you have your draw weight set to the desired level, it’s time to fine-tune the feel of the draw. This is a matter of personal preference, and there is no right or wrong way to do it. Some archers prefer a smooth, easy draw, while others prefer a more aggressive draw that feels like it’s pulling back on a heavy weight. There are a few things you can adjust to tweak the feel of the draw:
1. The Cam System
The cam system on your compound bow is what determines the draw cycle. Different cam systems will produce different feels, so it’s important to experiment with different ones until you find one that you like. Some cam systems are designed to produce a smooth, easy draw, while others are designed to produce a more aggressive draw. If you’re not sure which cam system is right for you, ask your local archery pro for advice.
2. Draw Length
The draw length of your bow is the distance between the nocking point on the string and the back of the grip. Draw length is a critical factor in determining the feel of the draw. If your draw length is too short, the bow will feel heavy and difficult to draw. If your draw length is too long, the bow will feel light and easy to draw, but you may not be able to hold it at full draw for very long. It’s important to get your draw length set correctly before you start to fine-tune the feel of the draw.
3. Let-Off
Let-off is the percentage of draw weight that is reduced at full draw. Let-off makes it easier to hold the bow at full draw, and it can also affect the feel of the draw. Bows with higher let-off percentages will feel lighter and easier to draw, while bows with lower let-off percentages will feel heavier and more difficult to draw. Again, it’s a matter of personal preference, so experiment with different let-off percentages until you find one that you like.
4. String Angle
The string angle is the angle at which the string enters the cam. The string angle can affect the feel of the draw and the speed of the bow. A higher string angle will produce a smoother, easier draw, but it will also slow down the bow. A lower string angle will produce a more aggressive draw, but it will also speed up the bow. It’s important to find a string angle that balances the feel of the draw with the speed of the bow.
5. Limbs
The limbs on your compound bow are what determine the draw weight. Limbs are available in different weights, so you can choose the ones that will give you the desired draw weight. In addition to the weight, the limbs can also affect the feel of the draw. Limbs made from different materials will produce different feels. For example, carbon fiber limbs are lighter and stiffer than aluminum limbs, which can produce a smoother, easier draw. It’s important to experiment with different limbs until you find ones that produce the feel of the draw that you like.
| Draw Weight | Maximum Draw Length | Let-Off | String Angle | Limbs |
|---|---|---|---|---|
| 50-80 lbs | 28-32 inches | 60-80% | 15-30 degrees | Carbon fiber, aluminum, or wood |
Factors Affecting Draw Weight Selection
Selecting the appropriate draw weight for your compound bow is crucial for both comfort and effectiveness. Several factors influence this decision:
1. Age and Physical Strength:
Younger or less physically strong individuals typically require a lower draw weight to avoid strain and injury.
2. Bow Type:
Different bow types (e.g., recurve, longbow) have varying draw weight ranges. Match the draw weight to the intended bow.
3. Intended Use:
Consider the purpose of the bow. Higher draw weights are suitable for hunting, while lower weights may suffice for target shooting.
4. Comfort and Control:
The draw weight should allow for a smooth and controlled draw. Discomfort or excessive fatigue indicates an inappropriate weight.
5. Arrow Velocity:
Higher draw weights generate greater arrow velocity, resulting in flatter trajectories and increased accuracy at longer distances.
6. Shooting Form:
Proper shooting form is essential for efficiency and accuracy. An excessively heavy draw weight can compromise form, leading to inconsistent shots. It’s recommended to start with a lower draw weight and gradually increase it as your strength and technique improve.
| Suggested Draw Weight | Body Weight |
|---|---|
| 30-40 lbs | 80-120 lbs |
| 40-50 lbs | 120-160 lbs |
| 50-60 lbs | 160-200 lbs |
