Duration: 8:51

This video demonstrates the process of sighting in a Vortex Viper shotgun red dot sight on a Mossberg 500 20 gauge shotgun. The instructor, Caleb from Brownells, uses Federal Grand Slam turkey loads at approximately 25 yards, emphasizing the importance of a stable rest and using a target with a shoot-n-see overlay. He details how to measure shot patterns, calculate optic adjustments using the manual's chart, and make incremental changes to achieve a precise zero. The process highlights the tactile nature of the optic's adjustments and provides practical advice for shotgun hunters and shooters.

Quick Summary

To sight in a Vortex Viper shotgun red dot, use a stable rest, fire a shot, measure the pattern's center, and calculate adjustments using the optic's click value from the manual. For example, at 25 yards, each click might move the point of impact 0.25 inches.

Frequently Asked Questions

What is the recommended method for sighting in a shotgun red dot sight?

The recommended method involves using a stable rest to minimize shooter error, firing a single shot, measuring the center of the pattern, and then calculating optic adjustments based on the distance and the optic's click value. Repeat as necessary for fine-tuning.

How do you calculate sight adjustments for a Vortex Viper shotgun red dot?

Consult the optic's instruction manual for its specific click value (e.g., 0.25 inches per click at 25 yards). Measure the distance between your shot pattern's center and your desired point of impact, then use this information to determine the number of clicks needed for windage and elevation.

What ammunition and shotgun were used to sight in the Vortex Viper red dot?

The video used Federal Grand Slam 3-inch turkey loads and a Mossberg 500 20 gauge shotgun. The setup included a turkey choke.

What tools are essential for sighting in a shotgun optic?

Essential tools include a stable shooting rest, a tape measure for precise measurements, and a Sharpie marker for marking targets. Having the optic's instruction manual with its adjustment chart is also crucial.
