How to Sight in a Rifle Scope for 100 Yards?
The scope, as the “invisible assistant” in modern shooting sports and hunting activities, plays a crucial role in helping shooters aim precisely and improve their shooting accuracy.
However, to make it shine in real-world situations, your scope cannot be taken out and expected to accurately shoot. It needs to be calibrated, especially at a 100-yard distance, where you need to make it “listen” and precisely target according to your instructions. Now, let’s talk about how to sight in a rifle scope for 100 yards to ensure every shot hits the target.
Part 1. Why Sighting in Your Rifle Scope is Important?
Sighting the rifle scope is a fundamental skill for every shooter, ensuring that the scope is properly aligned with the firearm. Even with high-end scopes, without proper calibration, shooting accuracy will be significantly reduced.
At a 100 yard range, the adjustment of the scope becomes particularly crucial, as it is a common medium-range distance in many shooting activities, and even a slight error can impact the final result.

Step 1. Necessary Tools for Sighting in Rifle Scope
Before you begin sighting in a rifle scope for 100 yards, make sure you have the following tools prepared:
- Target paper: Choose clearly marked target paper to accurately observe where the bullets hit.
- Screwdriver: Used to adjust the scope’s windage (left/right) and elevation adjustment knobs.
- Firearm: Ensure the firearm and scope are properly matched and that the firearm is in good condition.
- Gun rest or tripod: Stabilizes the firearm to prevent unnecessary vibrations and deviations during shooting.
Step 2. Choose the Right Shooting Position
Before starting to sight in your scope, you should choose an appropriate shooting location. A 100-yard distance is suitable for testing most rifles and scopes, so selecting a shooting range that provides a 100-yard distance is very important.
When choosing a shooting position, ensure the environment is safe and free of unnecessary distractions.
Additionally, make sure the area is flat to avoid any instability during shooting, which is crucial for calibrating the scope.
Step 3. Install and Prepare the Scope
Make sure your scope is correctly mounted on the rifle. Use high-quality scope mounts and secure screws to avoid any loosening. During installation, ensure the center of the scope aligns with the rifle’s sight line.
Step 4. Initial Aiming
After mounting the scope, the next step is to do initial aiming. This is typically done at a closer distance, usually within 25 or 50 yards. At this range, use a paper target to aim and ensure the scope’s view aligns with the target.
Once your rifle and scope are successfully aligned with the target, take a few shots to see if the point of aim matches the point of impact.
Step 5. Adjust Windage and Elevation
When shooting at 100 yards, the trajectory of the bullet is closely affected by factors such as wind speed and temperature. Therefore, adjusting the windage and elevation on the scope is crucial.
- Windage Adjustment: Wind speed can affect the flight path of the bullet, especially at longer distances. Most scopes have a windage adjustment knob that allows you to correct deviations caused by wind speed changes.
- Elevation Adjustment: The elevation knob is used to adjust the vertical deviation of the bullet. When you notice that the target is not hitting the correct position after initial shots, adjust the elevation knob to correct the vertical offset.
When making adjustments, carefully observe the results after each change and fine-tune as necessary until the bullet accurately hits the target.
Step 6. Fine-tuning and Testing
After completing windage and elevation adjustments, take several rounds of shots to test the effectiveness of the scope’s calibration. Ensure that the point of aim closely matches or directly aligns with the point of impact after each shot.
Sometimes, environmental conditions (such as wind speed, humidity, etc.) can affect the scope’s performance. Therefore, take multiple shots and gradually fine-tune the scope until you achieve optimal shooting performance at 100 yards.
Importance of a High-Quality Scope
When calibrating, using a high-quality scope is extremely important. A low-quality scope may cause blurred vision or inaccurate adjustments, affecting shooting precision. Choosing a scope with precise calibration mechanisms and a stable optical system is key to ensuring you can make accurate shots at 100 yards.
For example, Shotelex rifle scope uses advanced optical technology and precise calibration design to ensure every detail provides the best shooting experience for the shooter. Whether it’s clarity, brightness, or adjustment accuracy, it meets the needs of shooters at 100-yard distances.
Part 4. Common Mistakes to Avoid When Sight in a Rifle Scope
1. Ignoring Stability
One of the most common mistakes is not using a gun rest or tripod to stabilize the firearm. Shooting without a stable platform causes unwanted vibrations, which can significantly affect the calibration process.
Even the slightest movement during shooting can result in inaccurate adjustments, leading to errors that can be difficult to correct.
2. Over-Adjusting
It’s tempting to make large adjustments when things don’t seem right, but over-adjusting is a mistake that can actually worsen the problem. Making too many changes at once can amplify the deviations, making them harder to fix.
Instead, adjust incrementally and test after each change. This way, you can identify which adjustments are effective and which ones need more fine-tuning.
3. Failing to Check the Shot Result
After each shot, it’s crucial to check where the bullet actually hits the target. If you don’t inspect the shot placement, you may end up making incorrect adjustments.
For example, if the shot is low and left, but you mistakenly think it’s high and right, your adjustments will be wrong. Always verify the point of impact and adjust accordingly to avoid unnecessary mistakes.
Part 5. Tips for Maintaining Rifle Scope Accuracy
1. Regularly Check and Calibrate the Scope
Just like any precision instrument, your scope needs regular maintenance to stay in optimal condition. Over time, factors like recoil, temperature changes, and environmental conditions can affect your scope’s alignment.
It’s a good practice to check and calibrate your scope regularly, ensuring that it is always ready for precise shooting when you need it.
2. Ensure the Firearm Is Stable and Clean Before Calibration
Before you begin calibrating, make sure your firearm is in stable condition. A clean and properly maintained gun ensures that your shooting results are accurate and reliable.
Dirt or debris in the barrel, or even a loosely fitted scope mount, can lead to calibration errors. It’s important to clean your gun and check the scope mounting before starting.
3. Be Patient and Adjust Gradually
Calibration isn’t a process to rush through. Take your time, adjust in small increments, and test after each change. A rushed calibration could lead to big errors and an inaccurate scope. The goal is to make small, thoughtful adjustments, patiently working toward perfect alignment.
4. Check for Loosening Before Every Use
Before each shooting session, take a moment to check if the scope has become loose or has shifted in its mount. Even minor loosening can affect the accuracy of your shots.
Tighten the screws and ensure that the scope is firmly secured in place. This is especially important after a heavy recoil shot or a long shooting session.
Final Words
Sighting a scope is a fundamental skill every shooter must master, especially at 100 yards, where precision is critical. Through proper installation, adjustments, and testing, you can ensure your scope performs at its best, enhancing shooting accuracy.
When selecting a scope, choosing a high-quality product that suits your needs is key to success. Shotelex, as a professional rifle scope supplier, with its exceptional optical performance and precise calibration features, can help you achieve unparalleled accuracy at 100 yards.
