[QUOTE="JBM, post: 58779, member: 1969"] I keep seeing articles about these very, very long shots. As much as I'd like to be able to believe, it seems to me that most of them use quite a bit of ammunition to hit the target. In the article "Trials and Tribulations of Making the Long Shot" (at [url="http://slrharbor.com/)"]http://slrharbor.com/)[/url], there is this little tidbit: [ QUOTE ] It took five trips to Montana, 1,000 rounds of ammo, and Ken’s excellent spotting and coaching before I finally got the job done, shooting a dog at 2,110 yards. [/ QUOTE ] If I read that right, he shot over 1000 times before he hit the target at greater than 2000 yards. I may be labeled as a heretic for saying this, but I don't think that's accuracy -- it's perseverance. Just for the fun of it, I simulated a group of 28 feet and 1000 rounds. [I had to simulate it, I've never shot this far. And for you math types, it is normally distributed with sigma of 8. I'm using a normal distribution as an example. I don't know how much of an approximation this is.] This comes out to an accuracy of 16 MOA [somebody check my math to make sure]. Sure enough there is a shot close to the center. You can see the group here: [url="http://www.eskimo.com/~jbm/temp/shots.pdf"]http://www.eskimo.com/~jbm/temp/shots.pdf[/url] We see some nice groups posted here, but I've not seen one at 2000 yards yet -- any takers?
