Adjusting your Bushnell scope properly is essential for achieving precise shots and making the most of your firearm’s capabilities. Whether you’re sighting in a new scope or fine-tuning an existing setup, correct adjustments ensure your point of aim matches your point of impact. This guide walks you through the process step-by-step, covering everything from initial setup to troubleshooting common issues.
What You’ll Need
- Your Bushnell scope mounted securely on your firearm
- A stable shooting rest or bench
- Target paper with clear aiming points
- A firearm with the appropriate ammunition
- Tools for scope mounting (if needed, e.g., screwdrivers or Allen wrenches)
- Optional: A wind meter or rangefinder for advanced adjustments
Step-by-Step
- Secure Your Firearm and Setup a Stable Shooting Position: Use a bench rest or sandbags to minimize movement. Stability is key to consistent shots and accurate adjustments.
- Mount the Bushnell Scope Correctly: Ensure the scope is properly mounted and tightened according to manufacturer specifications. The reticle should be level and eye relief comfortable.
- Choose an Appropriate Target Distance: For most rifles, 100 yards is standard for zeroing. Use a target with clear markings to identify bullet impacts.
- Fire a Group of Three to Five Shots: Aim at the center of your target and shoot a group to see where the bullets are hitting relative to your aim point.
- Analyze the Shot Group: Determine the average point of impact (POI) of your group. This is where your bullets are hitting on the target.
- Make Elevation Adjustments: Locate the elevation turret (usually the top dial). If your shots are hitting low, turn the turret to move the reticle down (often clockwise); if shots hit high, move the reticle up (counterclockwise). Each click typically moves the point of impact by 1/4 MOA (Minute of Angle) or a specific value noted on the scope.
- Make Windage Adjustments: Locate the windage turret (usually the side dial). If shots land left of center, adjust the turret to move the reticle right, and vice versa. Adjust in small increments and note the direction recommended on the turret cap.
- Fire Another Group to Verify Adjustments: Shoot another 3-5 shot group at the same distance to confirm the point of impact has moved closer to your aim point.
- Repeat Adjustments as Needed: Continue making minor windage and elevation adjustments until your point of aim matches your point of impact reliably.
- Lock Turrets (If Applicable): Some Bushnell scopes feature turret locks to prevent accidental movement. Engage these once zeroed to maintain settings.
- Adjust Reticle Illumination (If Equipped): If your scope has an illuminated reticle, set brightness for comfortable viewing without glare.
- Record Your Zero Settings: Note the turret positions or settings for your preferred ammunition and distance. This can save time if you need to re-zero later.
Common Mistakes
- Adjusting Turrets in the Wrong Direction: It’s common to turn the dials the opposite way needed. Always check turret markings and directions before adjusting.
- Failing to Stabilize the Rifle: Shooting off-hand or unstable surfaces leads to inconsistent groups, making adjustments unreliable.
- Not Accounting for Parallax: Parallax error can cause aiming discrepancies at different distances. Use the parallax adjustment ring if your scope has one, especially at longer ranges.
- Making Large Adjustments Too Quickly: Big jumps in adjustment can overshoot the zero, wasting time and ammunition.
- Skipping Group Shooting: Adjusting after a single shot is inaccurate; always shoot groups to find the average POI.
- Ignoring Environmental Factors: Wind, temperature, and lighting conditions affect bullet trajectory and can skew zeroing if not considered.
Tips
- Use Consistent Ammunition: Different ammo types can impact point of impact. Zero your scope with the ammo you intend to use regularly.
- Mark Your Settings: Use tape or a marker to note your zeroed turret positions for quick reference.
- Adjust in Small Increments: Typically 1/4 MOA clicks give fine control. Smaller adjustments reduce the risk of overshooting.
- Check Eye Relief Regularly: Consistent eye relief ensures the reticle appears the same and reduces parallax issues.
- Practice at Various Distances: After zeroing at your primary distance, confirm point of impact at other common ranges.
- Keep Turret Caps Tight: Prevent dirt and moisture from entering and maintain turret integrity.
Troubleshooting
If your adjustments don’t seem to move your point of impact, consider the following troubleshooting steps:
- Check Scope Mounting: Loose or improperly aligned mounts can cause inconsistent results. Re-tighten rings and verify alignment.
- Verify Turret Functionality: Some scopes feature resettable turrets or locking mechanisms. Ensure turrets are not locked or stuck.
- Confirm Ammunition Consistency: Different lots or brands can alter impact points. Use the same ammo for zeroing and testing.
- Inspect for Damage: Look for dents, scratches, or internal damage to the scope that could affect performance.
- Account for Environmental Conditions: Wind or unstable weather can cause erratic shot placement. Choose calm conditions for zeroing.
- Parallax Setting: Incorrect parallax adjustment can cause apparent shifts in the reticle relative to the target. Adjust the parallax knob or ring if your scope has one.
- Consult the Manual: Bushnell scopes vary by model. Review the user manual for model-specific turret directions and features.
Frequently Asked Questions
- How often should I adjust my Bushnell scope?
- Adjust only when changing ammunition, shooting distance, or if you notice a consistent shift in point of impact. Regular checks before shooting sessions are recommended.
- Can I adjust my scope without a shooting rest?
- While possible, using a stable rest improves accuracy and helps make precise adjustments. Off-hand adjustments may lead to inconsistent results.
- What does 1 click on my turret equal in terms of bullet movement?
- Most Bushnell scopes use 1/4 MOA per click, meaning each click moves the bullet impact approximately 1/4 inch at 100 yards.
- Why does my scope have a parallax adjustment?
- Parallax adjustment eliminates apparent reticle movement when your eye shifts, improving accuracy at varying distances.
- Can I adjust my scope for windage and elevation simultaneously?
- Yes, but it’s best to adjust one axis at a time and test shots to isolate changes and ensure accuracy.
- What if my turret won’t turn?
- Check for turret locks or caps that need loosening. If stuck, consult the manual or a professional gunsmith to avoid damage.
By following these steps and tips carefully, you can confidently adjust your Bushnell scope to achieve accurate and consistent shooting performance. Regular maintenance and mindful adjustments will ensure your scope performs optimally for years to come.
