yeah, I was okay for a number of years - don’t recall exactly how many.
I started shooting when I was 10 years old. I think I made it to either late 30’s or maybe 40 before the tinnitus set in permanently.
mquinn55 described it quite well. Please take note.
Although, to the point some here are making - I do agree that shooting some guns (a small variety) once or twice (ever) without hearing protection helps you understand just how loud they really are, but I would not make a habit of doing it.
Note: The most painful (noise wise) gun I have ever fired without hearing protection was a .30-30 Marlin lever action. Not only loud, but a sharp crack, too. I was also firing a .44 Mag Marlin lever action that same day - it was quite loud, too, but nowhere near as painful as the .30-30. Lesson to be learned: In general, firing faster bullets without hearing protection will do more hearing damage.
