Not sure why. I tried it from 2 different computers with no issue. If you still can't get it, just go to youtube and search for sharkshooter2011. You can find the video there.
great video, but perpetuates some myths as well. his book is fantastic (and you can get it in electronic form these days). The myths have become that he made these great arial shots from the hip, but in his book he stresses his use of the sights. He may have done some trick shots from the hip (eg his fanning the hammer speed shoots), but he continually stresses aimed fire.
The NRA museum is worth a visit. I went one time and didn't allow enough time to see it all. Lots of cool history there. They have a nice 50yd indoor range, too...
