Power of a .22LR

[In-Yo-Grill]

Are phone books the only thing being used to experiment? What about a box of dirt? I wonder if 12"x12" would be enough. May need to try it out this weekend.

I read an article were a 60 grain 22lr round penetrated 16-24 inches of ballistic gel at 200 meters. Article was titled lethality of the .22 LR (field test).

Basically.... He used layers. Armored vehicles are defended in the same way against RPG rockets and high-caliber anti-tank weapons. M-1 Abrams armor is composed of layers of plate steel, ceramics, glass, plastics, or air, that fragment on impact when hit by a rocket. Theoretically, composite armor could absorb a shaped-charge explosion with 6" of layers that 12" of solid AND slanted plate/block steel couldn't stop.

It's because of geometry and round normalization.

When the round impacts the first plate, it's displaced from it's trajectory, striking the second plate with a less effective angle of attack. That makes the subsequent plates much more effective since the plates are angled. The round striking a 1" plate is actually meeting 1 - 2" of effective armor.

The .22 caliber bullet will always fair well in penetration compared to it's power. It's like an ice pick.

1' of dirt will stop a .22 easily

Railroad ties will stop all handgun rounds easily, even 10mm, .45, .357 SIG etc.
