The Box O’ Truth #14 – Rifles, Shotguns, and Walls

In our last tests shooting walls, we tried to line up 4 walls that were 2 feet by 2 feet. It turned out that the 5.56 deviated so much from its course after the first wall, that it was almost impossible to hit the other walls to test penetration. So, we built bigger walls.

I recently visited the antigovernment protests in Bangkok and was able to talk them into selling me some of the homemade body armor that they make using old x-ray film for plates. I would like to send one of the vests to you for testing.” I told him I would be glad to test [...]
