I screwed up once and got some ringing from it...learn the hard way. Actually I forgot the hearing protection, and decided to "make my own" - I had a collection of guns to shoot, and being dumb figured, "well, maybe the 22 will be quiet" and I will just use it. (The others were a 45 AUTO,30-'06, and a 45-70). Well, it was a 22-250, and my ears didn't like it at all. One shot, and that was it for me. I made some earplugs out of tissue paper - and it toned down the ambient sound pretty good - tried another 22 round, it was tolerable, not too loud at all. So I continued on that day, about 15 rounds of 30-'06 and maybe 5 or so more of the 22, and 5 or so of 45-70, and can't remember but not too many 45 autos (didn't like the trigger on it - some S&W I think with a realllly bad, super-stiff trigger). Anyhow, as usual things are quiet[er] when you have hearing protection on, and when you take them out/off you can hear good again. Well, I took my POS ones I made out, and everything remained quiet!! I couldn't hear much at all! It took THREE DAYS for me to start hearing normally again, had a ringing the whole time, and to this day. The ringing has substantially gone down over the years - used to be pretty bad - especially with a yawn or such - it would make a bunch of weird higher pitch vibratory sounds in the ear - from all the damaged nerve endings sending false signals and such I presume. I was dumb and was so obsessed with shooting, that I finally had an opportunity to shoot, and forgot the protection. (I rarely shot before that time yet wanted to all my life - but my parents are absolutely anti-gun) I decided to go try it, and I continued because when I put my self-made protection on, it made it quiet so I figured it would be okay. But it wasn't because when I took them off...everything remained quiet. As much as I like shooting, i am just going to have to side with I like hearing more. What would you rather do: Hear, or Shoot, or BOTH. I learned a lesson back then, and now I know better - BOTH is what I choose for now on.
