Sound Barrier question?

[Snipeshot11]

i dont have a chronograph, but every time i shoot my gun my ears pop, does this have anything to do with breaking the sound barrier?

I doubt it... its just the sound of the gunshot... reason for me being slightly deaf on my right ear... too much shooting at 30 bar I guess. Cant imagine whats gonna happen when I ramp it up to 40 bar

you should get some of these ear plugs... you can get about 5 pairs for 2 dollars where ever they sell guns and ammunition

the difference in sound is that sub sonic goes "boom" where super sonic makes a crack, just like a whip. i don't use earmuffs much, i normally just use a silencer, although that does not help with sonic crack. also i normally shoot subsonic because it is more accurate and less loud. although in my town guns going off at random times is obviously not frowned upon.
