The Box O' Truth #1 - The Original Box O' Truth - Page 1

Having some time for study of this fascinating sport, I built the "Box O' Truth".

The purpose of the Box is to test the penetration of various rounds.

People often say, "I think...". "I suppose...", "I bet...", when discussing facts like penetration of ammunition.

There is only one way to know how much a certain round penetrates.

You must shoot it into a medium and see for a fact.

This is the Box.

My shooting buddy, Tman and I took it to the range with a variety of guns and ammo. Here's what we did.

First, we loaded the box with 12 sheets of 5/8 sheetrock, which is also called wallboard in some areas.
Since it takes 2 sheets per wall, this is the thickness of 6 interior walls.

Why twelve? It seemed like a good number and I thought it might stop most rounds.
I was about to learn something.

First, I shot it with my M-17 S&W, .22 LR HP. It penetrated 6 sheets and bounced off the seventh sheet.
That would be the equivalent of 3 interior walls.
And that's only a .22 pistol.

Long story short, we proceeded to shoot several rounds and they all penetrated all 12 sheets and exited.

This is the entrance of the last sheet.

Notice that the XM-193 is tumbling.

We pulled the sixth sheet and that's about where it first tumbled.

We then replaced the sheetrock with something tougher, 3/4 inch Ponderosa Pine boards.

Here I am shooting a .45ACP at the box.

We fired several rounds and saw the following Penetration:

.22 Long Rifle (Wildcats) - 4 boards and bounced off 5th board.

9MM JHP (Federal) - 8 boards, bounced off 9th.

.45ACP (Federal Hydrashocks) - 7 boards, bounced off 8th.

Amazingly, none expanded at all. The nose just filled up with pine.
