I have purposefully shot a few magazines during a session only a couple times to remind myself of how loud it really is. Should I plan on doing it more often? Or is it not worth the damage to my ears, and I will be able to handle the noise if the time ever curses me?
...I'm sorry, could you repeat that a bit louder, maybe a lot louder?
Good grief, man, are you serious? To quote my kid's texting: "OMG".
I fired a .38 (S&W .357 seven shooter but had .38's in it) once without hearing protection out in a field. I did in once. That was enough for me to learn not to ever do that again, at least not just for shots-n-grins.
Insofar as being able to handle it if you ever needed to shoot without "ears", well, Mr. Adrenaline will likely not let feel anything or hear much of anything painful during the exchange. Then again, those who have been there and done that could elaborate.
