Look for the discolored case.
Annealed per military requirement. This ammo has been annealed, so you know it meets true military specs. Unlike your standard civilian round, the military requires visual proof of the annealing on the case, causing the case to appear discolored. This is done intentionally to meet military requirements for overall durability and strength in the completed round.
