Hello everyone, I am a World War II reenactor, and I only shoot blanks off a few times every year. I don't know too much about hearing damage but I have been told this wouldn't even be a problem. For a few days out of the year I have some people around me shoot off k98s, mp40s, garands, and some thompsons. Maybe even and mg42 or larger. I shoot a G43 and nobody else really uses ear protection but am wondering if it's a bad idea.
