300 Blackout VS 762x39 Part 2

This is a follow up to the 5.54x39 vs 556 vs 300 blackout vs 7.62x39. I really just wanted to get closer to the same barrel lengths and ammo selection. These were not available to us during the original video. I'm a big fan of the 7.62x39 and hoped to help prove the 300 blackout is its equal. Every ammo was designed for a specific role. The 300 blackout is living up to all the hype I have been hearing.
