The 8.6 Blackout significantly outperforms the .338 ARC in barrier penetration, demonstrating superior performance against concrete and mild steel. Its 1:3 twist rate enables impressive bullet expansion and wound cavities, especially with subsonic loads, while the .338 ARC struggles in these areas. The 8.6 Blackout also benefits from standard AR-10 magazine compatibility, offering higher capacity than the .338 ARC's reliance on .400 Legend magazines.
