Duration: 14:21

This video presents a ballistic gel test of Sim-X Defense Core .45 ACP ammunition. The reviewer, experienced in firearms testing, evaluates its performance through a clothing barrier and into gel blocks using chronographs. The results indicate significant fragmentation and limited penetration, leading to a negative recommendation for self-defense use.

Quick Summary

The Sim-X Defense Core .45 ACP ammunition demonstrated poor performance in ballistic gel tests, showing immediate fragmentation and limited penetration (4.5-5.75 inches). Averaging 1812 fps from a 5-inch barrel, the projectile broke apart extensively, making it unsuitable for self-defense according to the reviewer.

Frequently Asked Questions

What were the key findings of the Sim-X Defense Core .45 ACP ballistic gel test?

The Sim-X Defense Core .45 ACP ammunition exhibited immediate fragmentation and limited penetration in ballistic gel tests, with projectiles breaking apart significantly upon impact. This resulted in unpredictable terminal ballistics and was deemed unsuitable for self-defense by the reviewer.

What velocities were achieved with the Sim-X Defense Core .45 ACP ammunition?

From a 5-inch barrel 1911, the 72-grain Sim-X Defense Core .45 ACP averaged 1812 fps. From a 3.8-inch barrel G30, a velocity of 1661 fps was recorded, with challenges in obtaining consistent readings due to muzzle blast.

How did the Sim-X Defense Core .45 ACP perform in terms of penetration and expansion?

The ammunition showed immediate fragmentation rather than controlled expansion. Penetration was limited, with the 1911 shot reaching about 4.5-5 inches and the G30 shot around 5.75 inches in ballistic gel after passing through a clothing barrier.

What is the core of the Sim-X Defense Core ammunition made of?

The core is described as a proprietary polymer with characteristics of a non-Newtonian fluid. In ballistic gel, it appeared 'gooey' or 'slimy' and broke apart extensively, with the recovered core from the .45 ACP weighing approximately 13.0 grains.
