interior home walls do nothing

Published on March 28, 2026
Duration: 1:18

This video emphasizes the critical importance of understanding projectile behavior within a home environment to prevent over-penetration. It highlights that standard interior walls offer minimal resistance to bullets, increasing the risk of unintended harm to loved ones. The instructor strongly advocates for hollow-point ammunition for home defense due to its design for controlled expansion and energy dump, significantly reducing the risk of over-penetration compared to Full Metal Jacket (FMJ) rounds.

Quick Summary

Interior home walls offer minimal resistance to bullets, with standard FMJ rounds capable of penetrating 18-20 layers of drywall. For home defense, hollow-point ammunition is crucial as it expands on impact, maximizing energy dump and significantly limiting over-penetration, thus protecting unintended individuals.

Frequently Asked Questions

Why is over-penetration a major concern in home defense?

Over-penetration is a major concern because standard interior home walls offer minimal resistance to bullets. A projectile like Full Metal Jacket (FMJ) can pass through multiple walls, posing a severe risk to unintended individuals within or beyond the home.

What type of ammunition is recommended for home defense to prevent over-penetration?

Hollow-point ammunition is strongly recommended for home defense. It's engineered to expand upon impact, maximizing energy transfer to the target and significantly limiting the projectile's ability to penetrate through multiple barriers.

Can Plus P ammunition be used for home defense?

While Plus P ammunition offers increased power, it can also increase the risk of over-penetration. For home defense, especially in dwellings with multiple occupants, it's generally advisable to avoid Plus P if over-penetration is a primary concern, and opt for loads designed for controlled expansion.

What are the risks of using Full Metal Jacket (FMJ) ammunition for home defense?

Using Full Metal Jacket (FMJ) ammunition for home defense is highly discouraged. FMJ rounds are designed for deep penetration and can easily travel through interior walls, increasing the likelihood of hitting unintended targets and causing severe collateral damage.
