Shooting high with a scope is a frustrating problem that can significantly impact accuracy. This issue, where your shots consistently land above your point of aim, stems from several potential causes. This guide will delve into the most common reasons why your scope is shooting high and provide practical solutions to get your rifle back on target.
Understanding Point of Impact (POI) vs. Point of Aim (POA)
Before diving into solutions, it's crucial to understand the difference between Point of Impact (POI) – where your bullet actually hits – and Point of Aim (POA) – where your crosshairs are aimed. When your POI is consistently above your POA, you're experiencing a high shot.
Common Reasons Why Your Scope is Shooting High
Several factors can contribute to your scope shooting high. Let's break them down:
1. Scope Mounting Height:
- Problem: Incorrect scope mounting height is a primary culprit. If your scope is mounted too high, the trajectory of the bullet will naturally arc higher than intended.
- Solution: Lowering your scope mounts is often the solution. Consider using lower rings or bases to bring the scope closer to the boreline of your rifle. This reduces the distance the bullet needs to travel before clearing the scope, resulting in a lower POI.
2. Scope Adjustment Issues:
- Problem: Incorrect adjustments to the scope's elevation turret. A simple mistake in dialing in elevation can lead to high shots.
- Solution: Double-check your scope's elevation adjustments. Many scopes utilize a system where one click equates to a specific adjustment (often in MOA or MIL). Carefully verify your adjustments are correct and consistent. Consider resetting the scope to zero and starting the adjustment process again from scratch.
3. Ammunition Inconsistencies:
- Problem: Variations in ammunition – including bullet weight, powder charge, and even manufacturing inconsistencies – can affect trajectory.
- Solution: Use a consistent batch of ammunition during zeroing and sighting-in processes. Ensure you're utilizing ammunition specifically designed for your rifle caliber. Experimenting with different types of ammunition can alter the POI.
4. Incorrect Zeroing Procedure:
- Problem: Improper zeroing techniques can lead to inaccurate results. This is especially crucial for longer-range shooting.
- Solution: Follow a proper zeroing procedure. Start at a close range, progressively increasing the distance to accurately adjust your scope’s settings. Use proper shooting techniques, aiming precisely, and paying careful attention to wind conditions.
5. Environmental Factors:
- Problem: Wind, temperature, and even humidity can significantly affect bullet trajectory. Higher altitudes can also impact the performance.
- Solution: Account for environmental factors during sighting-in. Use weather data to help estimate wind drift and temperature changes to the bullet's flight path. Shooting in consistent weather conditions during zeroing is ideal.
6. Issues with the Rifle Itself:
- Problem: Problems with the rifle's action, barrel, or stock can also cause inconsistencies.
- Solution: This requires a thorough inspection. Any issues with the rifle's mechanics should be addressed by a professional gunsmith.
Troubleshooting Tips
- Start with the basics: Before making major adjustments, ensure your rifle is properly cleaned and lubricated.
- Document your adjustments: Keep detailed records of any changes you make to your scope or rifle.
- Seek professional help: If you're struggling to resolve the issue, consult a professional gunsmith or experienced shooter.
By systematically investigating these potential problems and employing the suggested solutions, you can effectively troubleshoot why your scope is shooting high and regain accuracy in your shooting. Remember, consistent practice and attention to detail are vital for successful marksmanship.
