Understanding how to adjust your scope's elevation is crucial for accurate shooting. Whether you're a seasoned hunter or a novice marksman, knowing which way to turn the elevation turret to raise or lower your point of impact is fundamental. This guide will break down the process, ensuring you're always on target.
Understanding Elevation Adjustments
The elevation turret on your riflescope controls the vertical point of impact of your bullet. It works by physically changing the angle of the scope's reticle relative to the barrel. This seemingly small adjustment translates to significant changes at longer ranges. Most scopes use a system of clicks, allowing for precise adjustments. Each click corresponds to a specific amount of adjustment, typically in minutes of angle (MOA) or milliradians (mils).
-
MOA (Minutes of Angle): 1 MOA equals approximately 1 inch at 100 yards. Therefore, a 1 MOA adjustment will move your point of impact 1 inch higher or lower at 100 yards, 2 inches at 200 yards, and so on.
-
Mils (Milliradians): Mils are another common unit of measurement. One mil approximately equals 3.6 inches at 100 yards. This means a 1-mil adjustment moves your point of impact about 3.6 inches at 100 yards, 7.2 inches at 200 yards, and so on.
Which way to turn for elevation adjustments? This is where the confusion often arises. The universal convention is:
Up is Up, Down is Down.
-
To raise your point of impact (move the bullet higher on the target): Turn the elevation turret up. This is usually counter-clockwise (left).
-
To lower your point of impact (move the bullet lower on the target): Turn the elevation turret down. This is usually clockwise (right).
This is true for the vast majority of scopes, but always double-check your scope's manual to confirm. Some specialized scopes might have reverse or unconventional adjustments.
Factors Affecting Elevation Adjustment
Several factors besides the turret adjustment itself can affect your point of impact:
-
Ammunition: Different ammunition loads will have slightly different ballistic characteristics, impacting point of impact. Use consistent ammunition for accurate elevation adjustments.
-
Environmental Conditions: Wind, temperature, and altitude can all significantly affect bullet trajectory and require elevation adjustments to compensate.
-
Scope Mounting: Improper scope mounting can lead to inaccurate zeroing and inconsistent elevation adjustments. Ensure your scope is securely mounted and properly aligned with the rifle's bore.
-
Rifle Condition: A poorly maintained rifle, with issues like a loose barrel or damaged action, can affect accuracy and throw off elevation adjustments.
Zeroing Your Scope: A Step-by-Step Guide
Zeroing your scope involves adjusting the elevation (and windage) turrets to match your point of aim with your point of impact. Here's how:
-
Securely Mount Your Scope: Ensure your scope is correctly mounted and tightened to the recommended torque specifications.
-
Fire a Test Group: Fire three to five shots at your target at a known distance (typically 25-100 yards for initial zeroing).
-
Assess the Impact: Note where your shots landed on the target. The center of your group represents your point of impact.
-
Adjust the Elevation Turret: Based on where your shots landed, adjust the elevation turret to move your point of impact towards the center of the bullseye. Remember: Up is up, down is down!
-
Repeat the Process: Continue firing test groups and adjusting your elevation turret until your point of impact is consistently in the center of your target.
-
Verify at Longer Ranges: Once zeroed at a shorter range, verify your zero at longer distances to account for bullet drop.
Case Study: Troubleshooting Elevation Issues
Let's say you're shooting at 100 yards and your shots consistently land 3 inches low. Since 1 MOA is roughly 1 inch at 100 yards, you'll need to adjust your elevation turret up by 3 MOA. If your scope uses 1/4 MOA clicks, you'll need to turn the elevation turret up by 12 clicks (3 inches * 4 clicks/inch = 12 clicks).
Conclusion: Master Your Elevation
Mastering elevation adjustments is key to accurate shooting. By understanding the basic principles of "up is up, down is down," paying attention to environmental factors and using a systematic zeroing process, you can ensure that your scope is always dialed in for optimal performance. Always refer to your scope's manual for specific instructions and adjustments. Remember consistent practice and attention to detail will refine your skill in making elevation scope adjustments.
