Anders Behring Breivik, the Norway shooter being charged for killing 68 people at a political youth camp near Oslo, wrote in his 1,500-page manifesto detailing his massacre plans that he purchased his ammo from an unnamed U.S. supplier for $550. The supplier amassed 10 30-round ammo clips from other disparate suppliers, which Breivik used for his .223-caliber rifle. He wrote that he could have bought the large rounds in Sweden, but that it was much cheaper to buy them in the U.S. He did, however, buy some clips legally for a Glock handgun in Norway, so that he could use them to practice at local firing ranges. His manifesto shows he carefully plotted out the massacre, writing that he was preparing to bring as much ammo as a soldier would need in battle.
