Published on November 1, 2019
Duration: 8:05

This video tests Magtech's 5.56mm 62gr FMJ ammunition using ballistic gelatin. Fired from a 10.5-inch upper, the round showed significant yaw and minimal fragmentation, with a penetration of 13.6 inches. Fired from a 16-inch barrel, the same ammunition demonstrated notable fragmentation and disruption, with a deepest fragment at 13.1 inches and total penetration exceeding 13 inches. The instructor deems it an adequate, though not ideal, choice for home defense and good range ammunition.

Quick Summary

Magtech 5.56mm 62gr FMJ ammunition shows varied terminal performance based on barrel length. From a 10.5-inch barrel, it exhibits minimal fragmentation and 13.6 inches of penetration. From a 16-inch barrel, it fragments significantly, exceeding 13 inches of penetration, making it an adequate choice for home defense.

Frequently Asked Questions

How does Magtech 5.56mm 62gr FMJ perform in ballistic gelatin from a short barrel?

From a 10.5-inch barrel, Magtech 5.56mm 62gr FMJ showed minimal fragmentation, with the bullet squishing its rear end and extruding a small amount of lead. It achieved 13.6 inches of penetration and created a temporary stretch cavity of about 3x6 inches, with significant yaw contributing to the cavity.

What are the terminal ballistics of Magtech 5.56mm 62gr FMJ from a 16-inch barrel?

When fired from a 16-inch barrel, the Magtech 5.56mm 62gr FMJ demonstrated significant fragmentation, scattering lead chunks. Penetration exceeded 13 inches, with the deepest fragment found at 13.1 inches. The temporary stretch cavity was estimated at 7.5x4 inches, indicating much better terminal performance.

Is Magtech 5.56mm 62gr FMJ suitable for home defense?

The instructor considers Magtech 5.56mm 62gr FMJ an adequate choice for home defense, particularly when fired from a 16-inch barrel, due to its ability to fragment and meet penetration standards. While not ideal, it performs better than some lighter FMJ rounds.

Does barrel length affect the fragmentation of Magtech 5.56mm 62gr FMJ?

Yes, barrel length significantly impacts fragmentation. From a 10.5-inch barrel, fragmentation was minimal. However, from a 16-inch barrel, the ammunition fragmented effectively, suggesting that higher velocity achieved with longer barrels is crucial for this bullet's terminal performance.
