Old hard drive penetration test (Subsonic .30-06)

[MacTech]

I just shot three hard drives taped together with fiberglass tape, the results were surprising....

The two loads tested were;
1; 14.9 grains of Trail Boss under a 165 grain Hornady SP
2; 17.9 grains of Trail Boss under a 130 grain Hornady SP

Four shots fired, two of each, distance, 25 yards

Load 2 punched clean through THREE hard drives
Load 1 punched through two, and severely dented the third

I wasn't expecting that kind of performance, I expected load 2 to get stopped, barely, by the third drive, and load 1 to stop in the second drive

Load 1 expanded better, the entrance hole in drive 2 looked to be almost .50 caliber, and no bullet fragments were found in drive 3, impact crater in drive 3 was the size of a half dollar.

Load 2 holes showed minimal expansion through all three drives, the exit holes were about .40 in diameter, bullet exited completely

A very impressive load, easy on the shoulder, yet capable of punching through three hard drives

I'll add some pics soon

Interesting. But then I have a fetish for reduced/subsonic loads.

I had fun with some hard drives back in the day. I didtn stack any behind each other, but found that 1 would stop a .22 from a rifle, but was not up to the task of stopping a .45.

I maintain that putting a big (insert favorite caliber here) caliber hole in a hard drive is the safest way to ensure that your data will NOT be recoverable.

Hard drives are my favorite target!




And yeah, great way to securely erase your data to boot.
