(get some ear protection)
+1 on that, and don't skimp on it. The range will probably (and should) require that and eye protection as well.
After decades of qualifying at least annually for work I have what the audiologist called a "notch" of hearing loss consistent with being exposed to gunfire. She didn't say that was the cause but did say it was characteristic of it.
I did always wear hearing protection but I guess it wasn't enough.
