Shooting Tip - Calculating Wind Hold

Published on January 6, 2014
Duration: 8:06

This expert-level guide from Gunwerks demonstrates the critical impact of environmental variables like altitude, temperature, and shot angle on long-range windage hold. It highlights the inadequacy of fixed turrets and showcases how advanced ballistic rangefinders provide the exact corrections needed for consistent accuracy. The instruction emphasizes the necessity of precise windage calculations for extended distances.

Quick Summary

For accurate long-range shooting, windage hold is critically influenced by altitude, temperature, and shot angle. Fixed turrets are often inaccurate as these conditions change. Ballistic rangefinders, like the BR2, provide exact windage corrections by factoring in these environmental variables.

Frequently Asked Questions

What factors affect windage hold in long-range shooting?

Windage hold is significantly affected by altitude, temperature (which influences air density), and the angle of the shot. These environmental variables alter the bullet's trajectory, requiring precise adjustments for accuracy.

Why are fixed yardage turrets often inaccurate for windage correction?

Fixed yardage turrets are calibrated for specific conditions. When altitude, temperature, or shot angle change, the ballistic performance of the bullet is altered, making the pre-set windage hold on a fixed turret inaccurate.

How does a ballistic rangefinder improve windage correction?

Ballistic rangefinders like the BR2 calculate precise windage solutions by factoring in real-time environmental data such as altitude, temperature, and shot angle, providing exact corrections needed for accurate long-range shots.

What is the impact of altitude on bullet trajectory?

Higher altitudes mean lower air density. This can affect bullet drop and drift. A rifle zeroed at a lower altitude may require different windage and elevation adjustments at higher altitudes due to these atmospheric changes.
