In this video we take a deep dive into .300 Blackout ballistics by putting both supersonic and subsonic loads through real-world testing. Using ballistic gel, chronograph data, and slow-motion footage, we measure velocity, expansion, and penetration to see how each load actually performs.
From short barrels to suppressed setups, we compare heavy vs fast and break down the strengths and trade-offs of each configuration. No hype — just data.
If you’ve ever wondered what .300 BLK really does on target, this is the test.
