Earlier this year I wrote an article about recording the sound of subsonic bullets using 40 caliber ammunition and learned a lot about the physics and technical aspects of these bullets. Since then I have recorded hundreds of subsonic bullets using smaller 22 caliber ammunition. Keep in mind I am no physics or ammunition expert but since talking with many knowledgable people about subsonic ammunition and actually recording them I have learned even more.
