King of the Mile
Also: KO2M
An extreme-long-range steel competition where targets stretch toward and past a mile, testing equipment and the shooter at the edge of supersonic flight.
King of the Mile, often abbreviated KO2M, is one of the marquee events in extreme long range competition. Shooters engage steel targets at distances that build toward and then exceed a full mile of 1,760 yards, where every variable in the ballistic chain compounds. Success at these ranges demands a rifle, cartridge, and load capable of carrying enough retained velocity to remain stable and lethal on impact after a long flight.
The mile is a meaningful threshold because most cartridges go transonic somewhere before it, and a bullet slowing through the speed of sound can destabilize and lose predictability. That is exactly the territory the relative long range thesis explores: matching cartridge and bullet so the projectile stays supersonic to the target, rather than simply reaching for ever-larger magnums.
