Supersonic ROCKS - Crudest 12g. Projectiles are no joke

In this video we propel rock slugs at 1500 fps and higher to see how effective they are at doing things and stuff. Zach, a viewer, came through and sent us these, which I was eager to test. How will these primitive projectiles react against different types of targets?
