Scorpion Ammo 5.56mm 55gr FMJ 500-Round Training Case Scorpion Ammo 5.56mm 55-grain FMJ is a brass-cased training load sold as a 500-round case, and it is available at Battlehawk Armory for range work. The case is 25 boxes of 20 rounds, loaded as 5.56x45mm M193 at a published 3,165 feet per second and 1,223 foot-pounds. The full metal jacket feeds cleanly and holds a stable path in AR-15 rifles and other 5.56-chambered firearms. Boxer primers and reloadable brass cases keep the empties worth saving after a practice session. The FMJ profile limits jacket fouling compared with exposed-lead bullets, which helps during high-volume drills. Scorpion builds the load for training, target practice, and range shooting rather than as a specialty hunting round. Five hundred rounds covers a long range day, a class, or a restock of a known practice load without mixing lots from separate orders. Each box stays at 20 rounds for easy magazine loading.
