It's the way my sound setup is, plus the fact I'm 85% enclosed inside that wooden shooting house that makes it echo, so it sounds louder than if I was out in the open air with no reflective surfaces for the sound to bounce off of. Also, I don't clip the audio like a lot of these "guntuber" guys do to make them sound "hollywood quiet" because that's not reality. They clip the audio at least 50% in editing the video to make them sound extra quiet while the gun is firing.
You can catch it every now and then during some of their videos, if they happen to start talking immediately after firing a round, you will notice their voices sound really quiet, then the audio suddenly jumps right back up and their voice is normal level. It's deceptive, but it brings in views. I'm not all about that. I'd rather people hear what they're actually getting. The way I setup my mic is as close to replicating how they sound in person inside that wooden building.
