This might seem like a dumb post but when I was a young bloke I thought I would conduct a penetration test of my own. I shot a variety of bullets from my 308 Win into a box of moist earth.

Now I soon learned that this is way too harsh of a medium to test bullet performance, but I did learn something.

The bullets included Hornady Interlocks, Remington Core Lokts, Nosler Accubonds and some Pro-Hunters. Unsurprisingly, fired from a distance of 10 yards they were all blown apart, torn to shreds.

Now like I said this turned out to be one of those not-so-well-thought-out things you do when you are young and inquisitive, and didn't return much in the way of meaningful results. But of nothing else it taught me one thing; if you push any bullet beyond it's design parameters, it will fail, bonded or not.
