Top takeaways

  1. Starline's 5.56x45mm NATO brass differs from their .223 Remington brass in metallurgy, making it harder at the base.
  2. Starline's .223 brass is safe to use in firearms chambered for either .223 or 5.56x45mm when loaded to .223 pressures.
  3. 5.56mm ammunition should only be used in firearms specifically labeled for 5.56mm to avoid safety issues.
