DO NOT just stuff some cleaning patches or cigarette filters in your ears, even for a couple of rounds - ASK ME HOW I KNOW! Years ago, I was out shooting with a friend down in Texas, in a caliche pit on his land. About the time we were packing things up to leave, he said, "Oh, almost forgot to shoot my new .357!" My headset was zipped up inside one of the range bags, so like an idiot, I just stuffed some cleaning patches in my ears, like I did when I was a kid shooting .22s. After all, he was just going to pop off six rounds, so no big deal, right? BIG MISTAKE. That was in the fall of one year, and the ringing in my ears didn't stop 'til the next spring.
