How loud is the supersonic crack of the bullet? I can hear it as it goes down range and perceive the location of the crack moves with the bullet, outside. But how loud is the crack inside? Considering it travels fifteen feet, inside, how loud is that? Is it perceptible over the suppressed report? Is it too fast for our hearing to perceive? Inside, without PPE, one hundred thirty decibels is loud! Does it cover the crack?
