Duration: 11:29

This video details a ballistic gel test of Buffalo Bore's 125-grain .357 SIG Low Flash ammunition. The test evaluates performance across two different barrel lengths, measuring muzzle velocity, penetration, and projectile expansion. The results demonstrate consistent and effective terminal ballistics suitable for self-defense applications.

Quick Summary

Buffalo Bore's 125-grain .357 SIG Low Flash ammunition demonstrated strong performance in ballistic gel tests. From a 4.5-inch barrel, it averaged 1516 ft/s and penetrated 15 inches with significant expansion. From a 3.5-inch barrel, it averaged 1427 ft/s and penetrated 17.75 inches, also showing substantial expansion.

Frequently Asked Questions

What are the key performance metrics for Buffalo Bore's 125-grain .357 SIG Low Flash ammunition?

In ballistic gel tests, this ammunition achieved average velocities of 1516 ft/s from a 4.5-inch barrel and 1427 ft/s from a 3.5-inch barrel. Penetration depths were 15 inches and 17.75 inches respectively, with significant projectile expansion observed.

How does barrel length affect the performance of Buffalo Bore .357 SIG Low Flash ammunition?

A longer barrel (4.5-inch) yielded higher velocities and slightly less penetration but greater expansion compared to a shorter barrel (3.5-inch), which achieved lower velocities but deeper penetration with substantial expansion.

What is the recommended projectile weight for .357 SIG self-defense ammunition?

The video suggests that 125-grain projectiles are optimal for .357 SIG, providing a good balance of penetration and expansion, and are preferable to lighter projectiles that may simply be 9mm bullets in a .357 SIG case.

What were the recovered projectile weights and expansion diameters for the Buffalo Bore .357 SIG 125gr Low Flash ammo?

From the longer barrel, recovered projectiles weighed 119.2 grains and expanded to approximately 0.555-0.582 inches. From the shorter barrel, they weighed 116.6 grains and expanded to about 0.502-0.505 inches.
