For context, out in the open country in a relatively flat area one can *easily* hear most centerfire rifles from 1-2 miles away and often much further. Shotguns are lower pressure and generally aren't as loud, and handguns even quieter still just due to the substantially reduced energy levels. Firearms, particularly rifles, are so loud that there's just a qualitative difference in the sound that's impossible to capture with standard audio gear.
