M193 lead-core Ball Ammo, an absolute STEAL of a deal here and now. 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.
PLEASE NOTE: While the 5.56x45mm round will fit in a .223 Remington chamber, 5.56 is a military round that is loaded to higher pressure than its .223 counterpart, and is therefore not recommended for use in rifles chambered for .223.
