Reid Henrichs, formerly of Tactical Response and known for his down-to-earth style has posted a video doing the testing that we all wish we could do through our own home. Using common calibers and ammunition, Reid and his training cohort from Valor Ridge put rounds through an actual house. Color me absolutely and insanely jealous.
The rounds themselves are fired through a window frame into a target and through at least two interior walls before encountering a final wall. Calibers shot include 5.56 NATO, .223 Remington, 7.62×39, and 9mm of various loadings including some of the most popular in use today such as M193 and various hollow-point and softpoint loadings.
As expected, few of the rounds penetrate through the complete home, but its important to note how many actually do and the behavior fo those that do not. Interestingly, many keyhole quickly and the deflection is incredible from groups that would be only a few inches at 50 yards. Further testing is conducted shooting directly into drywall, interior glass, and other interior materials.
The video itself is an excellent data point, but perhaps my favorite piece comes from a customer feigning a real estate listing:
“Minor water damage, Good insulation, Predrilled holes for holding pictures This amazing home could be yours! Give us a call.”
