We’ve had great success getting Hornady’s Critical Defense ammo to expand after passing through all sorts of crazy things – plastic, old garage rags, honey bears, Wal-Mart house brand grape jelly, spam, flour, e-mail, leather boots, canned vegetables, and more. So we figured it’s time for the ultimate test.
Rocks are hard and as we figure, tough on ammo. And you need to know if your ammo is going to perform should you ever encounter an evil d00d wearing a protective vest made of rocks.
When it came time to head to the range, we found actual rocks to be a bit problematic as they are big and heavy and somewhat uneven. And you know how scientific we are are about these things. We need repeatable uniformity. Sounds sophisticated doesn’t it? Repeatable uniformity.
So we elected to use some stone floor tile that we had laying around in the garage. Because it offers repeatable uniformity. And because it doesn’t seem to match any of the floor in our house. Apparently we stole it from the neighbors while they were distracted by the True-Green lawn guy.
We used our standard high tech methodology:
- Take random stuff to the range
- Bring lots of Hornady Critical Defense ammo
- Place cameras out there
- Get strange looks from people at the range
- Shoot through said random stuff
- Catch the bullet in our special wet pack blend (soggy newspaper and cardboard)
- Dig out the bullets
Surprisingly, both the .357 Magnum and .40 S&W Critical Defense loads expanded properly after passing through, well, rock more or less.
What’s the point you may ask?
The point is… Now you know not to put stone floor tile in your ballistic vest. It won’t help you.
