Great video! We spent the early part of this past week in the Klamath Basin doing the same thing.
Was amazing how many of those things we killed, and yet the next morning there would be just as many as the day before! I've got no idea as to the total number of rats that headed for the big Alfalfa field in the sky, but between rimfire and centerfire both, I went through almost 2700 rounds in three days of shooting. I'm glad I went crazy about three years ago and bought a LOT of 22 and 17 HMR! (No I don't have any for sale).
What kind of video camera were you using?
