I don't know if it's that guy's gun, the ammo, or his chronograph, but his velocity numbers are a lot lower than what I saw. I bought several boxes of this stuff from PSA and ran it over the chrono a few weeks ago, and it was pretty close to the speed claimed on the box - around 1,400 fps or so.
As with any ammo that expands really wide, penetration with this bullet seems a little shallow in my own testing, although fairly similar to the old Win Silvertips and the Barnes 115gr copper hollow points.
