The Bullet Test Tube does not accurately simulate tissue or gel. That is why there is a conversion-factor for figuring penetration of bullets shot into it. We might as well go back to shooting duxseal or lumps of clay, which it is more like than gel in consistancy, and which seem to favor higher velocity rounds.
