The hearing damage potential of subsonic rifle use is not insignificant. The gas volume and combustion products created by firing a subsonic intermediate rifle cartridge such as 300 BLK are still significant; the measured pressure and impulse magnitudes, and their durations, illustrate this fact. join_popup.classList.add('gbda-generate-lead'); 2023 Silencer Central.

I would be more interested in how the sound differs with both shooting supersonic since there has yet to be a "good" subsonic round made as far as terminal ballistics go.any comments in that regard?
