Duration: 19:55

This video provides a critical analysis of SimX DefenseCore ammunition by Boondock Ballistician. The instructor, demonstrating high expertise, uses professional chronograph equipment and ballistic gel tests to debunk marketing claims. The analysis reveals the ammunition's significant shortcomings in penetration and terminal ballistics, labeling it a gimmick with insufficient performance for self-defense applications.

Quick Summary

Expert analysis using professional chronographs and ballistic gel tests reveals SimX DefenseCore 9mm ammunition, despite high advertised velocities, fails to meet critical self-defense standards. With only 5-6 inches of penetration, it falls short of the FBI's 12-18 inch requirement, leading to its classification as a gimmick with insufficient terminal performance.

Frequently Asked Questions

What is SimX DefenseCore ammunition?

SimX DefenseCore is a lead-free 9mm ammunition featuring a proprietary synthetic non-Newtonian core. It's marketed as a high-velocity round, but independent testing reveals significant shortcomings in penetration and terminal ballistics.

How does SimX DefenseCore perform in ballistic gel tests?

In 10% ballistic gel tests, SimX DefenseCore 9mm only achieved 5-6 inches of penetration, falling far short of the FBI standard of 12-18 inches. The projectile's jacket also showed signs of collapsing.

Is SimX DefenseCore ammunition suitable for self-defense?

Based on expert analysis and standardized testing, SimX DefenseCore is considered a gimmick. Its insufficient penetration depth and lack of reliable expansion make it unsuitable for effective self-defense against typical threats.

What velocity does SimX DefenseCore 9mm achieve?

SimX DefenseCore 9mm ammunition achieves advertised velocities, with tested speeds around 2242 FPS from a pistol barrel and up to 2673 FPS from a Pistol Caliber Carbine (PCC) barrel.
