What's wild, is that I had the forethought to make a 'bunker' out of concrete blocks beforehand. Good thing because that flying object slammed the wall 8 inches beside and up from where my barrel was sticking out. The big piece that went up right I still haven't found.

That's nuts!  What's totally amazing is the speed of the projectile that goes left in the slow motion video.  it's FLYING!  And that's in slow motion.  Awesome video Eric.  I wish there was a way to get super close to it in slow motion, but that would be suicide...
