The Box O’ Truth #40 – Deflected Bullets and the Box O’ Truth

Many of us are hunters and some are combatants. We all know that if a bullet hits a hard object, it can be deflected in a completely different path than the one it was traveling before the hit. A question we want to test today is this: Are some bullets more resistant to being deflected than others? Sometimes a deer will be behind a brush and only allow a narrow area for a hunter to place a bullet through. Even then, that [...]

The Box O’ Truth #48 – Laminated Bullet Proof Glass – Rifles

In Part One, we shot some glass rated for pistols. Today, we will test some glass rated for rifles. This piece of glass is very heavy. Here’s the set-up, with the glass supported on three sides. It is rated NIJ III for Rifles, and is 20 X 20 inches, and 2 inches thick, and weighs 70 pounds. That’s heavy. We already know that this sheet of glass will withstand 5 rounds of .308, as that is what is required to [...]

Educational Zone #52 – Parkerizing a Sistema

When the Sistema pistols went through the system, I was able to acquire 2 of them and refinish them by painting them. They turned out really nice and are great shooters.I kept looking for another one, but they had dried up. I was disappointed.I had gone to Gander Mountain to ask my friend in the gun department if he thought they might get some more. He sadly told me that there were no more to be found.I walked away and [...]

Educational Zone #16 – Great Firearms – The 9 X 18 Makarov

The 9 X 18 Makarov is a fairly “new” round in the USA, but it has been a staple of firearms in Europe for a long time and is one of the most common police and military rounds in some countries.It is usually classified in power as between the .380 ACP and the 9 MM Parabellum.I believe that it is a little closer to the 9 MM in its hottest loadings. I have a couple of pistols that shoot this round. Here they [...]

Educational Zone #15 – The .455 Webley Revolver

Went to the range this fine morning and shot my .455 Webley revolver.It is a fine piece of history.It is marked “N.Z.” for New Zealand.It was converted to .45 Auto Rim to facilitate the use of .45 ACP ammo.This is it. Not very beautiful, but, as Forrest would say, “Pretty is as pretty does”.It shoots great. The design is a break-open design.You push down on the latch and the cylinder and barrel [...]

Educational Zone #146 – The S&W Model 25-2, .45 ACP Revolver

I have long wanted a S&W Model 25-2, .45 ACP revolver. I had seen one many years ago that was carried by a police officer I worked with and I fell in love with it. But he wouldn’t sell his, and I never could find a really clean one at a price I wanted to pay. I recently found a great example and bought it. Here it is, on the bottom. You will notice that it had the small N-frame grips, as compared to the Model 29 [...]

The Buick O’ Truth #2 – Windshields Outside/In

Police officers are often forced to fire from outside a vehicle into the passenger compartment through the laminated windshield glass.As I said earlier, a car is actually an incredibly effective lethal weapon, a fact violent suspects know and exploit.Sometimes to keep from being run over or to keep a fellow officer from being run over, and officer is forced to fire into the passenger compartment to try and stop the [...]

The Buick O’ Truth #3 – Pistols and Car Doors

A lot of officers have been trained to conduct a high risk stop behind the “cover” of their door, leaving it open while they kneel behind it with their weapon drawn.This seems like a very logical tactic, but as you are about to see, it actually doesn’t work in the real world. Notice that the pictures are taken from farther away this time. This is a safety precaution.Shooting a car is a fun thing to do, [...]

The Box O’ Truth #1 – The Original Box O’ Truth

This is the Box. 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 [...]
