Accurately adjusting the elevation on your riflescope is crucial for hitting your target at various distances. Whether you're a seasoned hunter, competitive shooter, or just starting out, understanding how to make these adjustments is essential for consistent accuracy. This guide will walk you through the process, explaining the mechanics, common mistakes to avoid, and best practices for dialing in your scope.
Understanding Scope Adjustments
Riflescope elevation adjustments are measured in minutes of angle (MOA) or milliradians (mils). Both units represent the angular measurement of the change in bullet drop at a specific distance. One MOA equals approximately one inch at 100 yards, while one mil equals approximately 3.6 inches at 100 yards. Knowing your scope's adjustment increments is vital. Most scopes are marked with clear indicators, often in 1/4 MOA or 1/8 MOA increments.
Identifying Your Scope's Adjustment System
Before making any adjustments, familiarize yourself with your scope's adjustment turrets. They typically feature:
- Elevation Turret: This turret controls the vertical adjustment of your point of impact. It's usually located on the top of the scope.
- Windage Turret: This turret controls the horizontal adjustment. It's usually located on the side of the scope. We'll focus on elevation here.
Many scopes also offer:
- Zero Stop: This prevents the turret from being turned past the zero point, preventing accidental adjustments.
- Locking Turrets: These allow you to lock your adjustments in place to avoid accidental changes.
Step-by-Step Guide to Adjusting Elevation
-
Safe Gun Handling: Always prioritize safe gun handling practices. Ensure the firearm is unloaded and pointed in a safe direction.
-
Establish a Zero: Before making any elevation adjustments, you need to establish a zero at a known distance (typically 25 or 50 yards). This means adjusting both the elevation and windage turrets until your point of impact is consistent with your point of aim. This is usually done using a target and sighting your shots.
-
Identify Your Bullet Drop: Once zeroed, you'll need to know how much your bullet drops at various distances. This information can be found through ballistic calculators, using your specific ammunition and rifle. This information will inform how many clicks you need to adjust your elevation.
-
Making the Adjustment: Locate the elevation turret. Most scopes use a clockwise rotation to raise the point of impact and a counterclockwise rotation to lower it. Carefully turn the turret the calculated number of clicks based on your bullet drop calculations and desired range. Remember, each click represents a specific MOA or mil increment.
-
Verify and Fine Tune: After making your adjustments, return to the range and verify your point of impact at your chosen distance. You may need to make minor adjustments to fine-tune the elevation.
Common Mistakes to Avoid
- Incorrect Turret Settings: Make sure you understand the click value (MOA or mil) of your scope and the bullet drop at your target distance.
- Ignoring Environmental Factors: Wind, temperature, and atmospheric pressure can affect bullet trajectory. Consider these factors when making adjustments.
- Not Zeroing Your Scope Properly: An inaccurate zero will lead to inaccurate elevation adjustments at longer ranges.
- Rushing the Process: Take your time and make careful, precise adjustments.
Maintaining Your Scope
Regular maintenance and cleaning will ensure the longevity and accuracy of your scope. Avoid excessive force when making adjustments. Clean your scope lenses regularly and store it in a safe, dry place.
By following these steps and understanding the fundamentals of scope elevation adjustment, you'll be well on your way to making more accurate shots at longer ranges. Remember, practice and patience are key.
