This guide details the critical Tall Target Test for verifying long-range rifle scope accuracy and tracking, as demonstrated by Gary from Paramount Tactical. It emphasizes precise setup, execution, and analysis to ensure your optic is plumb and its adjustments are true, using specific ammunition and tools like the MDT LRA Send It Level and Applied Ballistics app. This advanced technique is crucial for shooters demanding the highest level of precision.

Quick Summary

The Tall Target Test is a crucial procedure for long-range shooters to verify scope plumbness and accurate tracking of elevation adjustments. Performed at 100 yards with a level rifle and a tall target, it involves shooting groups at set MOA increments. Measuring actual impacts against expected values allows for calculating correction factors to improve ballistic solver accuracy.

Frequently Asked Questions

What is the purpose of the Tall Target Test in long-range shooting?

The Tall Target Test is a critical procedure to verify if a rifle's optic is mounted perfectly plumb (level) and to confirm that the scope's internal elevation adjustments track accurately and consistently. This ensures reliable performance at extended distances.

How is the Tall Target Test performed?

The test involves shooting groups at precise elevation increments (e.g., 5, 10, 15 MOA) on a tall target at 100 yards, while keeping the rifle perfectly level and the point of aim constant. Actual impact points are measured and compared to expected adjustments.

What tools are essential for the Tall Target Test?

Essential tools include a perfectly level rifle (using an anti-cant device), a precisely measured 100-yard distance, a tall target with clear markings, calipers for measurement, and a ballistic solver app to calculate and apply correction factors if needed.

Why is ammunition selection important for the Tall Target Test?

Ammunition consistency is vital. The video notes that specific lots of ammunition can exhibit erratic performance, affecting test results. Using reliable, consistent match-grade ammunition is recommended for accurate and repeatable data collection during the test.
