This guide details the technique for using a smart ballistic laser rangefinder for angled shots, as demonstrated by Brian Poor of Gunwerks Long Range University. It explains the physics behind angled shots, contrasts older rangefinder methods with modern smart devices, and provides steps for achieving accurate impacts by applying calculated ballistic solutions. The demonstration highlights the significant difference in accuracy between traditional and smart rangefinders on steep terrain.

Quick Summary

Smart ballistic laser rangefinders are essential for angled shots, unlike older geometry-based models. They integrate with apps to apply cosine correction to bullet drop, calculating accurate ballistic solutions. This prevents the overcompensation seen with methods like 'Rifleman's Rule', ensuring precise impacts on steep terrain.

Frequently Asked Questions

Why is a smart rangefinder better for angled shots than an older model?

Smart rangefinders like the Revic BR4 integrate with ballistic apps to calculate precise bullet drop compensation for angled shots using cosine correction. Older models using 'Rifleman's Rule' calculate horizontal distance, which overcompensates on steep angles, leading to low impacts.

What is the 'Rifleman's Rule' and why is it limited?

The 'Rifleman's Rule' or 'Map Distance' method uses geometry to calculate horizontal distance for angled shots. While useful for short ranges and shallow angles, it overcompensates at longer distances and steeper angles, causing shots to land low.

How does a smart rangefinder improve accuracy on steep terrain?

A smart rangefinder accounts for the altered effect of gravity on a bullet's trajectory during angled shots. By applying cosine correction to bullet drop, it provides accurate ballistic solutions, ensuring precise impacts where older methods fail.

Where can I learn advanced long-range shooting techniques?

Gunwerks Long Range University, directed by Brian Poor, offers classes in Cody, Wyoming, including specialized mountain shooting courses held on Sheep Mountain, providing hands-on training for complex shooting scenarios.
