Of the cartridges I'm aware of the Velocitor is likely the best choice for longest range. It has a 40 grain bullet, with a muzzle velocity of 1435 fps, and a ballistic coeficient of 0.128. If you fire it at an angle of exactly 30 degrees, it will come back down at 1763.3 yds with a velocity of 246.6 fps and energy of 5.4 ft-lbs. If you can find a PD that uses the same computer programs and stands still for 18.091 seconds, then it should all work out for the good (for you anyway!).
Oh, you were talking practical? Sorry, now at least we've set the theoretical max in any case... See this link if you are curious.
