The Underwood Ammo is designed to induce a large wound channel in soft tissue but allow penetration to FBI standards as well. The flutes cause massive cavitation in soft tissue. In bone and more dense tissue, however, the fact the bullet doesn't deform allows just the kind of barrier penetration it demonstrated through my ankle bones. So I think the injuries I suffered actually prove the bullet does what it claims to do, rather than refute it. That said, I would have much rather conducted the test in ballistic gelatin, not my left foot.
Were those pictures from before or after the doc flossed it and opened it up more?
I kinda feel like he mutilated your poor foot more than neccasary!
