Never mind the 1600+ yard (that is 0.91 miles) hit on a 12" diameter plate, the guy in the video (you get to see him toward the end) is someone I know. He has been to Boomershoot several times and Barb and I went to high school with his Aunt Shirley. He also used to shoot a lot of IPSC at the same events I went to.
Oh, he is also a gunsmith. I suspect he made the video to show off some of his work as well as his talent.
Thanks to Boomershooter Michael who had the following to say about the video:
Spring is coming, and a not-so-young man's thoughts turn to . . . Boomershoot. 
Well, close enough for now.
