Scattergun Science! Testing Diverter and Duckbill Chokes

Published on February 27, 2021
Duration: 9:28

This video tests the effectiveness of specialized duckbill and diverter chokes against a standard cylinder bore for shooting moving targets. Using a crossing dog drill with seltzer bottles, the test demonstrates that these chokes can create a wider horizontal pellet spread, leading to more centered hits. While the sample size is small, the specialized chokes appear to offer a measurable advantage for reactive shooting scenarios.

Quick Summary

Duckbill and diverter chokes flatten a shotgun's pellet pattern horizontally, creating a wider spread to improve hitting moving targets. Testing showed these chokes produced more centered hits and higher pellet density compared to a cylinder bore, indicating a practical advantage for reactive shooting.

Frequently Asked Questions

What is the purpose of duckbill and diverter chokes for shotguns?

Duckbill and diverter chokes are designed to flatten the shotgun's pellet pattern horizontally. This creates a wider spread, theoretically making it easier to lead and hit fast-moving targets by increasing the probability of connecting with pellets.

How were the shotgun chokes tested in the video?

The test used a 'Crossing Dog' drill where a seltzer bottle was pulled across a range at 10 yards. This simulated a moving target, allowing for direct comparison of hit patterns between a cylinder bore, a diverter choke, and a duckbill choke.

What ammunition was used for the shotgun choke test?

The test utilized Sellier & Bellot #4 buckshot. This specific ammunition was chosen because it is noted as being optimized for use with specialized muzzle devices like duckbill and diverter chokes.

Did the duckbill and diverter chokes prove effective?

Yes, the analysis showed that the diverter and duckbill chokes resulted in more centered hits and higher pellet density on the moving targets compared to a standard cylinder bore. This suggests they offer a measurable advantage for reactive shooting.
