operating environment, which, like his dope, will vary somewhat.

I must also thank the same unnamed SEAL for providing similar comeup data on the M8 Armor-Piercing Incendiary (API) cartridge, which does double-service because it's ballistically comparable to our next new round, the Raufoss Mk 211 Mod 0.

Developed in Norway and manufactured under U.S. government contract by Olin-Winchester, the Raufoss is an exploding armor-piercing round containing a tungsten carbide penetrator. This sophisticated design incorporates a chain of tiny, split-second events that combine for awesome effect. During acceleration, an incendiary mix in the tip compresses slightly and forms a pocket of air. When that air pocket compresses on impact, it ignites the incendiary mix, and that sets off a tiny RDX explosive charge. Then the tungsten steel penetrator jolts forward, white-hot sparks of zirconium particles follow to flash-ignite fuel or explosive vapors, while the bullet's soft jacket seals it against the impacted surface like a sloppy kiss. This would be impressive enough, but this 671-grain projectile's advanced design has also made it the most accurate military .50-caliber round in the inventory.

Please note: the Mk 211 Mod 0 is made in two grades, with the "A" grade offering better accuracy, firing on average a 3- to 4-inch group at 600 yards—1/2 MOA—from a test barrel, although the U.S. government considers a 6-inch group an acceptable standard. According to Norwegian data, the Raufoss round will penetrate up to 1/2 inch of armor at 1,100 yards. This Mk 211 Mod 0 has proved so popular among U.S. combat snipers that it's practically the only .50-caliber round they fire.

In 1999, the International Committee of the Red Cross (ICRC) unsuccessfully challenged combat employment of the Mk 211 Raufoss, claiming it violated the laws of war. Not only was this claim rejected, but on 14 January 2000, a
