I agree, I have also started using both ear plugs as well as over the ear , not only with outside rifle but also indoor pistol range tooFirst let me say I wear a hearing aid from years of wearing only ear muffs. I now wear dual hearing protection to protect the one good ear remaining. I primarily shoot long range Highpower rifle competitions so the noise factor is pretty high.
I use a set of custom molded ear plugs available through any of the big box sporting goods stores and a set of electronic ear muffs to hear range commands.
Protect those eyes and ears as much as you can as we only get one set of each.
