Your camera microphone probably has a noise filter that kills loud noises.

Btw what kind of camera were you using and did you have a different mic on it? Because I cant get good sound quality and all my videos make the gun sound super quiet.
Cameras seem to be hit and miss with this. I've seen cheap cameras record cannon sounds brilliantly while my brother's Canon 600D makes the loudest cannons sound like mouse farts.

It's not necessarily a quality thing. I don't know enough about audio recording to say what it is but I suspect it's to do with how an audio device records certain frequencies (i.e. some may record lows quite well but mids and highs poorly).

Often the problem with sound is Automatic Volume Control. The first sound wave sets the gain to almost nothing to prevent clipping and distorted sound. If you have a video editor, use a laptop running Audacity to record the sound (turn the gain way down to prevent clipping) and record your shot from a reasonable distance with a good external mic. After recording, use the Amplify function to set the peaks near 0. Use audio compression only a little if needed to add conversation to acceptable levels. Now you have a soundtrack with no quick muting due to the AVC. Replace the camera sound in your video editor.
