Yes, I did lean the rifle's stock on the window edge . I was just saying there was no front bag rest on a shelf or a rear rest , I did get as stable as I could . The point was I hit within about a 1/4 of an inch of where I aimed with one shot and I feel that was done because I was using a match grade rifle and load . I was very happy with the result .

There are some really excellent marksman that can shoot some really long distances, that said, I thinks its unethical as hell to shoot at an animal from those ranges. There are a lot of things that can happen out of your control between the shot and a bullet traveling 700-800 yards or more. If you are a good hunter, then get closer. Like the OP, I'm amazed at shows that continue to hide the poor shots and follow ups from those decisions.

Don't miss my point, some people are very capable of making the shot. To me, there is too much the can go wrong, like an animal moving or wind or whatever that can affect bullet placement and end up with a poor shot and a wounded animal. If that doesn't matter to you then fire away.
