How to Adjust Draw Weight on a Compound Bow (2026)

Quick Answer

Adjusting draw weight on a compound bow involves turning the limb bolts clockwise to increase weight or counterclockwise to decrease it, typically using an Allen wrench. Most compound bows allow 10-15 pounds of adjustment range without requiring a bow press, and each full turn of the limb bolts changes draw weight by approximately 2-4 pounds. Always turn both limb bolts equally (counting turns carefully) and never back them out more than the manufacturer’s specified maximum to avoid limb damage.

Key Takeaways

• Draw weight adjustment on compound bows is done by turning limb bolts with an Allen wrench, not by replacing parts
• Most bows offer 10-15 pounds of adjustment range from the factory peak weight
• Turn both top and bottom limb bolts equally, counting each rotation to maintain proper tiller
• Each full turn typically changes draw weight by 2-4 pounds depending on the bow model
• Never exceed the manufacturer’s maximum number of turns (usually 4-5 full rotations out from bottomed position)
• You can safely adjust draw weight at home without a bow press for most compound bows
• After significant draw weight changes (more than 5 pounds), retuning your bow improves accuracy
• Signs of excessive draw weight include shaking at full draw, poor form, and inability to hold steady aim
• Compound bow adjustment differs fundamentally from recurve bows, which require limb replacement to change weight
• Check your draw weight every few months as limb bolts can settle or loosen over time

What Is Draw Weight on a Compound Bow

Draw weight is the amount of force required to pull a bow back to full draw, measured in pounds. On a compound bow, this measurement refers to the peak weight you pull at the beginning of the draw cycle before the cams rotate and the let-off reduces holding weight. For example, a 60-pound compound bow requires 60 pounds of force at peak draw, but thanks to the cam system’s let-off (typically 65-80%), you only hold 12-20 pounds at full draw.

Draw weight directly affects arrow speed, kinetic energy, and penetration power. Higher draw weights launch arrows faster and hit harder, which matters for hunting larger game. However, more weight also demands greater physical strength and can compromise accuracy if you struggle to control the bow.

Key factors influenced by draw weight:

• Arrow velocity and trajectory flatness
• Effective hunting range and penetration
• Physical fatigue during practice sessions
• Accuracy and shooting form consistency
• Legal compliance for hunting specific game species

Understanding your bow’s adjustable draw weight range helps you optimize performance without exceeding your physical capabilities.

How Much Draw Weight Should I Use for My Size

Choose a draw weight you can comfortably draw 20-30 times in a practice session without fatigue or form breakdown. For most adult beginners, this means starting at 40-50 pounds for men and 30-40 pounds for women, regardless of body size. Physical fitness, upper body strength, and shooting experience matter more than height or weight when selecting appropriate draw weight.

General draw weight recommendations by purpose:

• Target archery beginners: 30-45 pounds
• Whitetail deer hunting: 40-50 pounds minimum (check state-specific minimum draw weight laws)
• Elk and larger game: 50-65 pounds
• Youth archers (ages 8-14): 15-25 pounds
• Archers over 50: 40-50 pounds (see our guide for hunters over 50)

Choose lower draw weight if you experience shoulder pain, cannot hold steady at full draw for 5-8 seconds, or notice your form deteriorating after a few shots. You can always increase weight as your strength improves. Starting too heavy creates bad habits that take months to correct and increases injury risk.

Can I Adjust Draw Weight Myself or Do I Need a Bow Shop

You can safely adjust draw weight yourself on nearly all modern compound bows without visiting a bow shop or using a bow press. The adjustment process requires only basic tools and takes 5-10 minutes. Limb bolt adjustment (the standard method for changing draw weight) does not require disassembling the bow or relieving string tension.

When you can adjust at home:

• Making changes within the bow’s advertised adjustment range (typically 10-15 pounds)
• Turning limb bolts that are not bottomed out or maxed out
• Working with bows manufactured after 2000 that have standard limb bolt systems
• Making incremental changes of 5 pounds or less at a time

When to visit a bow shop:

• You need to change draw weight beyond the limb bolt adjustment range (requires new limbs)
• The limb bolts are seized or stripped and won’t turn
• You’re unsure about your bow’s maximum safe adjustment range
• You want to verify proper tiller and timing after major adjustments
• The bow is a vintage or unusual model with non-standard adjustment systems

Most archers successfully handle routine draw weight adjustments at home. However, having a bow shop verify your work after your first adjustment builds confidence and ensures you haven’t made errors.

What Tools Do I Need to Adjust Compound Bow Draw Weight

The only essential tool for adjusting draw weight is an Allen wrench (hex key) that fits your bow’s limb bolts, typically 3/16-inch or 1/4-inch. Most compound bows use one of these two standard sizes, though some manufacturers include proprietary sizes. A bow scale for measuring actual draw weight helps verify your adjustments but is not required for the mechanical process.

Complete tool list for draw weight adjustment:

• Allen wrench set (metric and standard sizes covering 3/16″, 1/4″, 5mm, 6mm)
• Bow scale or draw weight gauge (optional but recommended, $20-60)
• Marker or tape (to mark starting bolt positions)
• Owner’s manual (lists maximum safe turns and bolt specifications)
• Bow press (only needed if changing limbs entirely, not for limb bolt adjustment)

Before starting, identify which size Allen wrench fits your limb bolts by testing each size. The correct wrench should fit snugly without wiggling. Using the wrong size rounds off bolt heads and creates expensive repair problems.

Mark your starting position by placing a piece of tape on the limb near each bolt or drawing a reference line. This lets you track exactly how many turns you’ve made and return to the original setting if needed.

How to Turn Limb Bolts to Increase Draw Weight

Turn both limb bolts clockwise (tightening direction) equally to increase draw weight, making the same number of rotations on the top and bottom limbs. Start by turning each bolt one full turn, then test the draw weight. Continue making equal adjustments in half-turn increments until you reach your target weight.

Step-by-step process:

1. Mark starting positions – Use tape or marker to note current bolt positions on both limbs
2. Loosen or tighten equally – Turn the top limb bolt one full rotation clockwise
3. Match the bottom limb – Turn the bottom limb bolt exactly one full rotation clockwise
4. Test the draw – Pull the bow back to check feel and effort required
5. Measure if possible – Use a bow scale to verify actual draw weight change
6. Repeat in small increments – Continue with half-turn adjustments until reaching target weight
7. Verify equal turns – Confirm both bolts received identical adjustments

Each full turn typically changes draw weight by 2-4 pounds depending on your bow model. Smaller bows and shorter axle-to-axle models tend to change more per turn, while longer target bows change less.

Common mistake to avoid: Never adjust only one limb bolt. Unequal limb bolt positions create tiller problems, causing the bow to shoot inconsistently and potentially damaging the cam timing system.

Always turn both bolts the same amount, even if it means making multiple small adjustments to dial in your exact target weight. This maintains proper limb balance and cam synchronization.

How Many Turns Can I Safely Adjust Draw Weight

Most compound bows allow 4-5 full turns out from the fully bottomed position before risking limb damage, but you must verify your specific bow’s maximum in the owner’s manual. Backing out limb bolts beyond the manufacturer’s specification can cause limb separation from the riser, catastrophic limb failure, or dangerous string breakage.

The safe adjustment range translates to approximately 8-20 pounds of draw weight change depending on your bow model. High-performance hunting bows typically offer 10-15 pounds of adjustment, while beginner and youth bows may offer 15-20 pounds or more.

How to find your safe limit:

1. Check the owner’s manual – Lists exact maximum turns for your model
2. Look for manufacturer markings – Some bows have warning labels on the limbs
3. Contact the manufacturer – Customer service can provide specifications if you lack documentation
4. Use the “threads visible” rule – If you can see more than 3-4 threads of the bolt shaft above the limb pocket, you’re likely near or past the safe limit

Warning signs you’ve gone too far:

• Visible gap between limb butt and limb pocket
• More than 5-6 bolt threads showing above the riser
• Unusual creaking or popping sounds when drawing
• Visible limb twist or asymmetry

If you need more draw weight reduction than your limb bolts allow, you must purchase lighter limbs for your bow. Exceeding the safe adjustment range to achieve lower weight risks serious injury from limb failure.

Difference Between Adjusting Draw Weight on Compound Bow vs Recurve Bow

Compound bows adjust draw weight by turning limb bolts that compress or decompress the limbs within a fixed range, while recurve bows require physically replacing the limbs with different-weight limbs to change draw weight. This fundamental difference makes compound bow adjustment a 10-minute home project versus a parts-replacement process for recurve bows.

Compound bow adjustment:

• Turn limb bolts with Allen wrench
• Adjustment range typically 10-15 pounds
• No parts replacement needed
• Completed in minutes at home
• Maintains same limb characteristics throughout range

Recurve bow adjustment:

• Remove and replace entire limb set
• Requires purchasing new limbs ($100-400)
• May need bow press for some takedown models
• Changes limb stiffness and feel
• Essentially creates a different bow

Some modern recurve bows (particularly takedown models) offer interchangeable limbs that make weight changes easier, but you still must buy and swap complete limb sets. Compound bows’ built-in adjustability is one of their primary advantages for archers who want flexibility without buying multiple sets of limbs.

The mechanical advantage of compound bow cams also means the actual draw weight you feel changes throughout the draw cycle, unlike recurve bows where weight increases linearly to peak at full draw. This makes drawing a compound bow smoothly a different skill than drawing a recurve.

Will Adjusting Draw Weight Affect My Bow Accuracy

Small draw weight changes (2-5 pounds) typically have minimal impact on accuracy for the same archer, but larger adjustments (10+ pounds) will change arrow flight, point of impact, and may require retuning. The bow’s mechanical accuracy remains the same, but your shooting form, anchor point consistency, and release execution often change when draw weight increases or decreases significantly.

How draw weight changes affect accuracy:

• Arrow spine matching – Heavier draw weights require stiffer arrows; your current arrows may be under- or over-spined after adjustment
• Sight settings – Increased speed from higher weight changes arrow trajectory, requiring sight adjustments
• Release execution – Lighter weight may cause premature release or punching; heavier weight may cause flinching
• Holding stability – Weight changes affect how steady you can hold at full draw
• Cam timing – Extreme adjustments can affect cam synchronization on dual-cam bows

After adjusting draw weight by more than 5 pounds, expect to spend a practice session re-establishing your groups and adjusting your sight pins. Your arrows will hit higher (if you increased weight) or lower (if you decreased weight) than before at all distances.

Best practice: Make draw weight changes during the off-season or at the beginning of a practice cycle, not right before a competition or hunting season. Give yourself 2-3 weeks to adapt to the new weight and retune your setup.

For most archers, accuracy improves when dropping to a comfortable draw weight because better form and steadier holding outweigh the minor trajectory differences from reduced arrow speed.

What Happens If I Max Out the Limb Bolts on My Compound Bow

Bottoming out the limb bolts (turning them fully clockwise until they stop) sets your bow to its maximum rated draw weight and is perfectly safe. This is the factory-intended peak weight position. However, backing the bolts out beyond the manufacturer’s maximum turns (usually 4-5 rotations from bottomed) risks limb separation, catastrophic failure, and serious injury.

When limb bolts are fully tightened (maxed in):

• Bow is at advertised peak draw weight
• Limbs are fully compressed against riser
• No safety concerns
• This is the starting point for measuring adjustment range

When limb bolts are backed out too far (maxed out):

• Limbs may separate from limb pockets during draw
• Risk of sudden limb failure and string release
• Potential for serious facial or hand injuries
• Voids manufacturer warranty
• May damage cam timing and synchronization

Most manufacturers design limb bolts to bottom out at the maximum safe compression point, making it impossible to over-tighten and damage limbs by turning them in too far. The danger zone exists only when backing bolts out beyond specifications.

If you’ve reached the minimum draw weight your limb bolts allow and still need less weight, you must purchase lighter limbs. Never exceed the maximum number of turns out specified in your owner’s manual, even if the bolts physically turn further.

How to Know If My Draw Weight Is Too Heavy for Me

Your draw weight is too heavy if you cannot smoothly draw the bow 20-30 times without fatigue, if you shake or struggle to hold steady at full draw, or if your shooting form deteriorates after a few shots. Physical signs include shoulder pain, inability to reach your anchor point consistently, and “punching” the release trigger instead of executing a smooth release.

Clear indicators of excessive draw weight:

• Shaking at full draw – Cannot hold steady for 5-8 seconds
• Inconsistent anchor point – Struggle to reach the same position each shot
• Shoulder hunching – Raising shoulder to help pull the bow back
• Premature release – Letting go as soon as you reach full draw because you can’t hold
• Target panic symptoms – Flinching or punching the trigger due to anticipation of the heavy pull
• Accuracy decline – Groups open up after 10-15 shots as fatigue sets in
• Next-day soreness – Shoulder, back, or arm pain lasting more than a few hours after shooting

The 20-shot test: If you cannot complete 20 consecutive shots while maintaining good form and consistent groups, your draw weight is too high for practice purposes. You may be able to draw the bow once or twice, but sustainable shooting requires a weight you can handle repeatedly.

Reduce draw weight by 5-10 pounds if you experience any of these symptoms. Shooting a lighter bow with perfect form produces better accuracy and more ethical hunting shots than struggling with excessive weight. Many successful bowhunters use 45-55 pounds effectively on large game, proving that perfect shot placement matters more than raw kinetic energy.

Do I Need to Retune My Bow After Changing Draw Weight

You should retune your bow after draw weight changes of 5 pounds or more, as the increased or decreased energy affects arrow spine dynamics, cam timing, and nocking point position. Small adjustments (2-3 pounds) rarely require retuning, but checking paper tune and verifying sight settings takes only 15 minutes and ensures optimal accuracy.

What to check after draw weight adjustment:

• Paper tune – Verify clean bullet holes; adjust rest if needed
• Cam timing – Ensure both cams hit the wall simultaneously on dual-cam bows
• Nocking point – May need slight adjustment up or down
• Sight pins – Will require adjustment for new arrow speeds
• Arrow spine match – Verify your arrows are still properly spined for the new weight
• Center shot – Confirm rest position is still optimal

Increasing draw weight makes arrows act stiffer (effectively increasing spine), while decreasing weight makes them act weaker. If you change weight by 10+ pounds, your current arrows may no longer be properly spined, causing erratic flight and poor groups.

Quick retuning process:

1. Shoot through paper to check arrow flight
2. Adjust rest position if tears show left/right issues
3. Walk back tune at 20-40 yards to verify centershot
4. Reset sight pins for new arrow speeds
5. Verify broadheads still fly with field points

For detailed tuning guidance, see our bow tuning resources. Most archers can complete basic retuning at home, but a bow shop can verify your work if you’re uncertain.

Common Mistakes When Adjusting Compound Bow Draw Weight

The most common mistake is adjusting limb bolts unequally, which creates tiller problems and ruins cam timing. Always count turns carefully and make identical adjustments to both top and bottom limbs. Other frequent errors include exceeding the manufacturer’s maximum adjustment range, using the wrong size Allen wrench that strips bolt heads, and failing to verify actual draw weight with a scale.

Critical mistakes to avoid:

• Unequal limb bolt turns – Creates tiller imbalance and cam synchronization problems
• Exceeding maximum turns – Risks catastrophic limb failure
• Wrong wrench size – Rounds off bolt heads, making future adjustments impossible
• Skipping the owner’s manual – Each bow has specific adjustment limits
• Adjusting only one limb – Never adjust just top or bottom; always both equally
• Making large jumps – Changing 10+ pounds at once without testing in between
• Not marking starting position – Makes it impossible to return to original settings
• Ignoring warning signs – Continuing to back out bolts when threads are excessively visible

The “one limb only” mistake: Some archers mistakenly believe they can fine-tune tiller by adjusting only one limb bolt. While this technically changes tiller, it also disrupts cam timing on most modern bows and creates more problems than it solves. Proper tiller adjustment requires equal limb bolt positions with tiller tuning done through limb pocket shims or professional limb work.

The “no measurement” mistake: Adjusting by feel alone without using a bow scale leads to overshooting your target weight. A $30 bow scale eliminates guesswork and helps you track exactly how much each turn changes your specific bow’s draw weight.

Always make adjustments in small increments (one turn at a time), test between changes, and document what you’ve done. Taking photos of bolt positions before starting gives you a visual reference if you need to reverse your changes.

Can Adjusting Draw Weight Damage My Bow Limbs

Adjusting draw weight within the manufacturer’s specified range cannot damage your bow limbs. However, backing out limb bolts beyond the maximum number of turns specified in your owner’s manual can cause limb separation from the riser, limb cracking, or catastrophic failure during draw. Over-tightening by bottoming out the bolts is safe and represents the bow’s designed maximum weight position.

Safe adjustment practices:

• Stay within manufacturer’s specified turn limits (typically 4-5 turns out from bottomed)
• Turn both limb bolts equally to maintain balance
• Make gradual changes rather than extreme adjustments
• Check for visible gaps between limb and limb pocket
• Listen for unusual sounds (creaking, popping) that indicate stress

Damage risk factors:

• Exceeding maximum turns out – Primary cause of limb separation and failure
• Unequal limb bolt positions – Creates uneven stress and potential cracking
• Seized bolts forced to turn – Can strip threads or crack limb pockets
• Extreme temperature changes – Adjusting frozen or heat-soaked bows stresses materials
• Corrosion or debris – Dirty bolt threads can bind and cause uneven pressure

Modern compound bow limbs are engineered to handle the full adjustment range safely. The limb bolts themselves serve as the safety mechanism by limiting how far you can compress or decompress the limbs. As long as you respect the maximum turns-out specification, you cannot damage limbs through normal draw weight adjustment.

If you notice any cracks, splinters, or delamination in your limbs after adjustment, stop shooting immediately and have a professional inspect the bow. These signs indicate either manufacturing defects or that the bow was adjusted beyond safe limits at some point.

How Often Should I Check or Adjust My Bow Draw Weight

Check your bow’s draw weight every 2-3 months during active shooting seasons, as limb bolts can settle or loosen slightly over time, especially on new bows. Verify draw weight before hunting season starts, after any period of storage longer than a month, and whenever you notice changes in arrow flight or shooting feel.

When to check draw weight:

• Before hunting season – Ensure you’re legal for your target game species
• After storage – Bows stored for months may have shifted
• New bow break-in – Check after first 100-200 shots as components settle
• After temperature extremes – Significant heat or cold can affect limb tension
• When accuracy changes – Unexplained point-of-impact shifts may indicate weight change
• After transport – Rough handling or shipping can loosen bolts

When to adjust draw weight:

• Strength changes – As you build or lose upper body strength
• Season transitions – Different weight for practice vs. hunting
• Injury recovery – Temporary reduction during shoulder or back rehabilitation
• Game species change – Adjusting for legal minimums or ethical requirements
• Form problems – Reducing weight to rebuild proper technique

Most archers find their optimal draw weight within the first season and make only minor adjustments afterward. However, life changes like aging, injury, or extended breaks from shooting may require revisiting your draw weight choice.

Keep a simple log noting your draw weight, limb bolt positions (number of turns from bottomed), and the date. This helps you track changes over time and quickly return to known-good settings if you experiment with adjustments.

For hunters, verify your draw weight meets state-specific minimum requirements well before season opens, giving yourself time to adjust and practice if needed.

Frequently Asked Questions

Can I adjust draw weight on any compound bow?
Nearly all modern compound bows manufactured after 1990 feature adjustable draw weight through limb bolts, typically offering 10-15 pounds of range. Very old bows and some specialty models may require limb replacement to change weight, but these are rare exceptions.

How much does each turn of the limb bolt change draw weight?
Each full turn of the limb bolts typically changes draw weight by 2-4 pounds, though this varies by bow model. Shorter axle-to-axle bows tend to change more per turn, while longer target bows change less. Test your specific bow to determine its rate of change.

Do I need to adjust both limb bolts the same amount?
Yes, always turn both top and bottom limb bolts equally, counting each rotation carefully. Unequal adjustments create tiller imbalance and disrupt cam timing, causing accuracy problems and potential equipment damage.

Will changing draw weight affect my arrow selection?
Draw weight changes of 10+ pounds may require different arrow spine. Increasing weight needs stiffer arrows, while decreasing weight needs more flexible arrows. Changes under 5 pounds rarely require arrow replacement.

Can I adjust draw weight with the bow strung?
Yes, limb bolt adjustment is performed with the bow fully strung and under tension. You do not need a bow press for standard draw weight adjustments within the limb bolt range.

How do I know my bow’s maximum safe adjustment range?
Check your owner’s manual for the specific maximum number of turns allowed from the fully bottomed position, typically 4-5 full rotations. If you lack documentation, contact the manufacturer or visit a bow shop for verification.

Should I adjust draw weight before or after setting up my bow?
Set your desired draw weight before final bow tuning, sight installation, and arrow selection. Draw weight affects all other setup parameters, so establish it first to avoid retuning multiple times.

Can temperature affect my bow’s draw weight?
Temperature changes affect limb stiffness slightly, but the effect is minimal (typically less than 1-2 pounds across extreme temperature ranges). Limb bolts may loosen or tighten slightly with temperature cycling, so check periodically.

What’s the difference between peak draw weight and holding weight?
Peak draw weight is the maximum force required during the draw cycle, while holding weight is the reduced force at full draw after let-off. A 60-pound bow with 75% let-off requires 60 pounds at peak but only 15 pounds to hold at full draw.

How long does it take to adjust draw weight on a compound bow?
The physical adjustment takes 5-10 minutes. However, testing the new weight, verifying with a scale, and making fine-tuning adjustments may take 20-30 minutes total for a complete, careful adjustment.

Will adjusting draw weight void my bow warranty?
No, adjusting draw weight within the manufacturer’s specified range is normal maintenance and does not void warranties. However, exceeding maximum adjustment limits or causing damage through improper adjustment will void coverage.

Can I increase draw weight beyond my bow’s rated maximum?
No, you cannot exceed the bow’s rated peak draw weight by tightening limb bolts beyond the fully bottomed position. The bolts stop at the designed maximum. To get higher draw weight, you must purchase heavier limbs or a different bow.

Conclusion

Learning how to adjust draw weight on a compound bow empowers you to optimize your setup for changing strength levels, different shooting purposes, and evolving skills without professional help. The process requires only basic tools, careful attention to equal adjustments on both limbs, and respect for your bow’s maximum adjustment range. Most archers successfully handle these adjustments at home, saving time and money while gaining deeper understanding of their equipment.

Start by locating your bow’s owner’s manual to verify the maximum safe adjustment range, then gather an Allen wrench set and optionally a bow scale. Mark your starting limb bolt positions, make equal adjustments to both limbs in small increments, and test between changes. Remember that each full turn typically changes weight by 2-4 pounds, and most bows allow 4-5 turns out from the fully bottomed position.

Choose a draw weight you can handle comfortably for 20-30 shots without form breakdown, even if that means starting lighter than you initially planned. Perfect form with a 45-pound bow produces better results than struggling with 60 pounds. As your strength and technique improve, you can gradually increase weight within your bow’s adjustment range.

After significant draw weight changes, plan to spend a practice session retuning your bow and adjusting sight settings. The investment of 30-60 minutes ensures your equipment performs optimally at the new weight. Check your draw weight every few months during active shooting seasons, as limb bolts can settle over time.

Take action today by locating your bow’s specifications, testing your current draw weight with a scale if available, and making adjustments if needed. Your accuracy, enjoyment, and long-term shooting success depend on finding the right balance between power and control.
