100lbs Kentucky Geode Vs 50 BMG (Bulletproof)

Published on January 29, 2025
Duration: 2:27

This video tests the ballistic resistance of a 100lb Kentucky geode against various calibers, from birdshot to .50 BMG. The geode demonstrates significant resistance, with smaller calibers causing superficial damage. Larger calibers like .308 Winchester begin to penetrate, and it ultimately takes a .50 BMG round to crack the geode open, revealing its quartz interior.

Quick Summary

A 100lb Kentucky geode was subjected to ballistic testing with calibers ranging from birdshot to .50 BMG. While smaller rounds caused superficial damage, it ultimately required a .50 BMG round to breach the geode, creating a distinct slice and revealing its quartz interior.

Frequently Asked Questions

What calibers were used to test the 100lb Kentucky geode's ballistic resistance?

The geode was tested against a range of calibers, starting with birdshot from a 12 gauge shotgun. Subsequent tests included .22LR, .380 Auto, 9mm Luger, 5.56x45mm NATO, .308 Winchester, and finally, the powerful .50 BMG.

How did the smaller calibers affect the 100lb geode?

Smaller calibers like birdshot, .22LR, and .380 Auto caused minimal damage to the geode. Birdshot resulted in surface damage without penetration, .22LR left a tiny impact mark, and .380 Auto chipped off a small chunk of rock.

Which caliber was ultimately successful in breaching the 100lb geode?

It took a .50 BMG round to successfully breach the 100lb Kentucky geode. This powerful round created a significant 'lemon wedge' slice, opening the geode and revealing its quartz interior.

What was the effect of the 5.56x45mm NATO round on the geode?

The 5.56x45mm NATO round did not penetrate the geode. Instead, it crushed the rock surface, creating hairline fractures and sending fragments down a segment of the geode without removing material.
