This video details a comprehensive ballistic test simulating bullet penetration through multiple layers of common house construction materials. The host, demonstrating high expertise in terminal ballistics, tests various calibers from .22 LR to .44 Magnum, as well as rifle rounds and shotgun loads, to determine how many simulated 'houses' each can penetrate. The findings offer practical insights into over-penetration concerns for self-defense scenarios.

Quick Summary

In a ballistic test simulating house walls, the 7.62x39mm AK-47 with hollow points penetrated all four simulated houses. The 10mm Auto also demonstrated significant penetration, reaching into the fourth house. Rifle calibers like 5.56 NATO and 5.45x39mm generally stopped in the third house, similar to some pistol rounds.

Frequently Asked Questions

How many layers of material were used to simulate a house wall in the test?

The experiment used eight wall panels, each constructed with layers of drywall, insulation, half-inch plywood, and siding. Two panels represented one 'house', simulating four houses in total for the penetration tests.

Which calibers penetrated the most simulated houses in the test?

The 7.62x39mm AK-47 with hollow points penetrated all four houses. The 10mm Auto also showed significant penetration, reaching into the fourth house, while several other calibers stopped in the third.

Did rifle calibers like 5.56 NATO penetrate more than pistol calibers?

Surprisingly, the Daniel Defense MK18 in 5.56 NATO stopped in the third house, similar to some pistol calibers like the 9mm and .40 S&W. The 7.62x39mm, however, penetrated further than most pistol rounds tested.

What was the performance of shotgun loads in the penetration test?

12 Gauge Birdshot penetrated only the first wall. #4 Buckshot stopped in the second house, while 00 Buckshot penetrated two houses. A 12 gauge slug penetrated three houses.
