Let’s unlock your potential and elevate your shooting skills.
Before diving into adjustments, understanding the components of your rifle scope is essential. Familiarity with these parts will enable you to manipulate the controls confidently and interpret your results accurately.
The objective lens is the large front lens, gathering light and determining the scope’s light-gathering capabilities. Its size affects the brightness of the image, particularly in low-light conditions.
The eyepiece is the lens at the rear of the scope where you position your eye. It adjusts the focus of the reticle and the image you see. Proper eye relief, the distance between your eye and the eyepiece, is critical for comfort and safety, preventing injuries from recoil.
The windage adjustment turret is usually located on the scope’s top or side. It’s used to correct for horizontal bullet drift caused by wind or to move your point of impact left or right.
The elevation adjustment turret, also typically located on the top or side, controls vertical adjustment. It’s used to compensate for bullet drop over distance, allowing you to hit targets at varying ranges.
If your scope incorporates parallax adjustment, it minimizes or eliminates the visual error caused by parallax. This feature is especially important at longer ranges, when your eye isn’t aligned with the scope’s optical center.
The reticle – the crosshairs or aiming point – is the focal point you use to align your shot. Reticles come in various designs, from simple crosshairs to complex reticles with holdover points for bullet drop compensation.
The magnification ring is a crucial component, enabling you to zoom in and out, adjusting the level of magnification. It gives you more detail on the target, making it easier to aim at a distance.
Key Terminology: Deciphering the Scope’s Language
To understand how your scope works, it’s essential to familiarize yourself with the terminology. This will help you interpret instructions, evaluate your adjustments, and communicate effectively with other shooters.
MOA (Minute of Angle)
MOA (Minute of Angle) is an angular measurement that helps measure the distance of shots from the point of aim. One MOA is approximately 1 inch at 100 yards. The higher the MOA, the larger the measurement.
MRAD (Milliradian)
MRAD (Milliradian) is another unit of angular measurement, often used in military and tactical scopes. One MRAD is roughly 3.6 inches at 100 yards.
Click Value
Click value refers to the amount the bullet’s impact will change at a set distance for each click of the windage or elevation adjustment. The value is dependent on the MOA or MRAD per click of your scope and the zeroing range. Scopes often come in ¼ MOA per click, meaning each click moves the bullet’s point of impact ¼ inch at 100 yards, or 1/8 MOA.
Zeroing
Zeroing refers to adjusting your scope so that your rifle hits at the desired point of impact at a specific range.
Parallax
Parallax is an optical illusion. It is the apparent movement of the reticle in relation to the target when the shooter’s eye is not perfectly centered in the scope.
Windage
Windage is a term describing the horizontal adjustment of the scope to account for wind effects or to move your shots left or right.
Elevation
Elevation represents the vertical adjustment, allowing you to compensate for bullet drop and aim higher or lower.
Decoding Your Scope’s Specifications
Every scope is engineered with specific performance characteristics. These specifications provide critical information to make precise adjustments. The scope manual, packaging, and markings on the scope itself are excellent resources to find this information. Understanding the click value (MOA or MRAD per click), total adjustment range (windage and elevation), and any parallax adjustment settings are all critical. For instance, knowing your scope’s click value enables you to make precise adjustments to correct for wind drift or bullet drop. If the manual cannot be found, look for labels or markings. For example, a “¼ MOA” marking on a turret indicates the value of each click adjustment.
Preparation: Setting the Stage for Success
Before you even touch your turrets, meticulous preparation is essential. Taking the time to set things up properly will prevent frustration and increase your odds of a successful zeroing session.
Gathering the Essentials
The first step is gathering all the necessary tools and equipment. Your selection of tools should ensure safety and smooth operations.
You will need your rifle and scope, ideally already mounted securely. Ensure the rifle’s action is clear and safe.
Next, select ammunition of the correct caliber and type. Using the wrong ammo may cause errors or, at worst, damage the rifle or scope.
Targets are a crucial component. Use appropriate targets suited for the zeroing process. Bullseye targets are popular, as are those with grid patterns.
A shooting rest or bench is a must for consistent accuracy. It will stabilize the rifle, minimizing unwanted movement and allowing you to focus on the adjustments.
Consider using a spotting scope or binoculars. They’ll allow you to observe your shots on target without having to walk downrange after every shot.
Eye and ear protection is a must! Safety comes first.
Keep cleaning supplies nearby to quickly clean your rifle if the barrel gets fouled.
Finally, have a screwdriver on hand in case adjustments are needed to the scope mounts.
Establishing a Safe Shooting Environment
The importance of safety cannot be overstated. Your safety and the safety of others are the top priorities.
Always adhere to all gun safety guidelines. Make sure the muzzle of the rifle is always pointed in a safe direction.
Choose an appropriate shooting range or safe location. Ensure there’s a sturdy backstop behind your target to catch bullets and prevent errant shots.
Be aware of other shooters and conditions, such as wind and light.
Scope Mounting Alignment: Setting the Foundation
While the scope should be mounted on the rifle prior to adjusting the scope, it’s important to briefly review how the scope is mounted.
Ensure the scope rings are correctly spaced, and the screws are properly tightened.
Make certain the scope is level with the rifle. Misalignment can create issues when making adjustments and may cause inaccurate shots.
Zeroing Your Scope: The Path to Precision
With preparation complete, you’re now ready to begin the zeroing process. This is where the science of the scope merges with the art of shooting.
Setting Up Your Target
Choose the appropriate zeroing range. A common starting point is 100 yards/meters. This distance offers a good balance between accuracy and ease of adjustment. Once you gain more experience, this can be adjusted.
Place the target at your chosen distance.
To accurately determine the distance, measure the distance between the firing line and the target using a rangefinder or other measuring equipment.
Initial Shots and Analyzing the Group
Assuming the rifle is in a stable rest, carefully load the rifle. Fire a group of shots, typically three to five. This will create a “group” on your target – a cluster of bullet holes.
Examine the shot group on the target, paying attention to its center. Where is the center of the group relative to your point of aim?
Identify the point of impact (POI) in relation to your point of aim (POA). This difference is the key to making the correct adjustments.
Adjusting Windage and Elevation: The Control Knobs
Now it’s time to make the adjustments. Locate the windage and elevation turrets on your scope. The owner’s manual will tell you exactly where they are.
Understanding the relationship between the turrets and their function is crucial. The windage turret controls horizontal movement, while the elevation turret controls vertical.
Calculate the required adjustments based on your group’s location. If your shots are, for example, two inches high and one inch right at 100 yards, you need to adjust the turrets accordingly. Refer to your scope’s click value to determine how many clicks to turn. If your scope has ¼ MOA clicks, and the POI is two inches high, you will need to turn the elevation turret eight clicks down (2 inches / .25 inches per click = 8 clicks). For the one inch to the right correction, you’d turn the windage turret four clicks left (1 inch / .25 inches per click = 4 clicks).
Making the adjustments is straightforward. Always make adjustments in the direction you want the bullet’s impact to move. Turn the turret in the appropriate direction: up/down, left/right.
Firing Subsequent Groups and Refinement
After making your initial adjustments, carefully fire another group of shots. Analyze the impact of the shots, again comparing the new point of impact with the point of aim.
Make further adjustments based on the new shot group. Continue to fine-tune until the point of impact is as close as possible to your point of aim.
Repeat the process until you have a consistently accurate zero at the desired range.
Beyond the Basics: Longer Distances
For shooters who intend to engage targets at different distances, you can zero at a different range to accommodate for trajectory. Knowing bullet drop at specific distances will allow you to refine your shooting even further.
Troubleshooting: Overcoming Common Issues
Even the most experienced shooters can encounter issues during the zeroing process. Here are some common problems and solutions.
Scope Not Adjusting
If the scope appears to not be adjusting, carefully examine the scope and scope mounting system.
Check the scope mounts to ensure they are securely fastened.
Ensure the adjustment turrets are unlocked.
The Reticle Not Centered
If the reticle doesn’t seem to be centered, make sure the scope is level with the rifle.
Double check the scope rings to ensure they are correctly aligned.
Scope Tracking Issues
If the scope exhibits tracking problems, the scope itself may be defective. Contact the manufacturer or seek professional assistance.
Consistent But Incorrect Grouping
If your shots are grouping consistently but still hitting the wrong point, shooter error may be to blame.
Consider your recoil management, breathing, and trigger control.
Check that your scope mounts are secure and not loose.
