Only topped by .44 Magnum and above I believe. Jeorge Sprave and Nathan Masters did a down and dirty video on this a while back. (It wasn't the most scientific of tests, but it does show the properties well enough) And Jeorge was using one of his usual giant *** slingshot contraptions with a huge ball. It wasn't penetrating power but stopping force. That might not be Nathan, buuuut I'm pretty sure it is. I'm pretty sure Chuck Norris was hiding in there somewhere too with all that coolness going on.
