Long-range shot data wanted: MV + POI

[David Bookstaber]

I want to put together an analysis that separates the SD of velocity from dispersion on a target. I'm looking for a data set with the following characteristics:

1. At least 20 shots from same gun, shooter, ammo, and session. Can be on a single target, or multiple targets if the point of aim on each target is known.
2. Muzzle velocity associated with each point of impact.
3. Target shot at a long enough range that vertical dispersion is much larger than horizontal. (To get that, the distance would probably have to be over 150 yards for rimfire, and depending on MV variance and BC it might need to be well over 1000 yards for centerfires.)

Any leads greatly appreciated!
