This video details a water drop test conducted on 11 commercial .410 slugs to assess their in-air stability. The test involved dropping slugs into a 14-inch water column and observing their trajectory. Results indicated significant performance differences, with Brenneke and Winchester Super X slugs performing best, while others like Sterling, Federal, and BPS slugs exhibited poor stability, tumbling, or sideways flight.

Quick Summary

A water drop test was conducted on 11 commercial .410 slugs to assess their in-air stability. The Brenneke 3-inch Magnum and Winchester Super X 3-inch slugs showed excellent stability, dropping straight. Conversely, Sterling, Federal, and BPS slugs performed poorly, tumbling or flying erratically, indicating potential issues with aerodynamic performance.

Frequently Asked Questions

What is a water drop test for firearms slugs?

A water drop test involves dropping a projectile, like a slug, into a tall column of water to observe its trajectory and stability. This method can provide insights into how the slug might behave aerodynamically in air, revealing issues like tumbling or excessive waggle.

Which .410 slugs performed best in the water drop test?

The Brenneke 3-inch Magnum and the Winchester Super X 3-inch .410 slugs demonstrated the best stability, dropping nearly straight down through the water column with minimal deviation. These slugs are considered to have better aerodynamic properties based on this test.

Which .410 slugs performed poorly in the water drop test?

Several .410 slugs, including Sterling, Federal, and both BPS variants (red and green), performed poorly. They exhibited significant instability, tumbling, turning backward, or skittering sideways, indicating poor aerodynamic design or manufacturing.

Can a water drop test accurately predict real-world slug performance?

While not 100% scientific, a water drop test offers a level of understanding of how slugs react. However, the presenter notes discrepancies with field testing, suggesting factors like velocity, weight, and transonic-to-subsonic transition are crucial for long-range accuracy not fully replicated by this test.
