You know I need to try this at the range with some of my guns.. I do know that I can get 5-7 shots out of 13 to hit a big standard shooting circle target at 100 yards. I've tried it a few times bracing the gun on a rest. And that was shooting my G23..Glock .40..with a 4.02in" barrel and wwb ammo. I just wanted to see if I could hit the target.. amazingly I did about half the time with the compact Glock. My buddy tried the same thing with a beretta 9mm and didn't hit once.. but I think I'm a better shot than him anyways.. perhaps I could have got the beretta to have hit too. .dunno.. 
I've been putting some thought into this and have come up with an idea. If there are trees or some other objects behind your ranges targets that you can use for reference, you could aim at a ridiculous range target, ( 100 - 500 yards) start low, aiming right at the target, you or an observer watching the fall of your shot and adjusting based on back ground aiming points.
If you keep notes of, firing lane, aim point, ammo, etc you should be able to repeat the shot at a later date on first try.
This is the way artillery works, indirect fire, it's not something that would have any PRACTICAL use, but it could win you some free beers if it works.
Make sure you consider the safety situation of your particular range, we don't want to be putting rounds over the berm. Start low and work up carefully.
