I never owned a set of ear protectors for shooting till about the mid 70's.
Worn then only if you found yourself on a crowded range with many shooters.
Otherwise, the bulky things were off.
.22, centerfire, rifle, pistol,,,,didn't matter.
Clay target, plinking, hunting, ect,,no ear protection.
Pure stupidity in 20-20 hindsite.
My older brother was the same way. Plus he went thru USMC Boot Camp and said they never worn ear protection on the range. Shot the M14s all the way through. Now wears 2 hearing aids.
We both started shooting indoor Bullseye pistol in the early 80's.
It was required for the course, as was eye protection, and one shot indoors w/o any would convince you that you'd need them anyway.
That was the way it was with most people then.
When it was qualification time for the Sheriffs Dept on the revolver course,,hearing protection wasn't a necessity,,wasn't mentioned.
I recall a few seasoned looking types sporting hearing protection at the time, but most of us youngins did have or feel we needed such a thing. Early 70's.
Ringing ears, periods of deafness,,,so that was just part of the shooting game.
Now the always present crickets and 'white' noise,,,,never any real piece and quiet.
Exploding entire rolls of caps on the side walk with Dad's ballpeen hammer as kids probably gave the degrading process a good start.
Loud machinery, other peoples music, ,,,Lot's of things happen to damage hearing.
A hearing aid now improves the left side ,,but even that I find a pain to wear anymore.
I've learned to live with it. It's kind of interesting to get your fast food order and see what your "OK" and head nod was in agreement to from the fast talking 16 y/o behind the counter.
Do the best you can to protect it and your eyes.
It's really an uncomfortable life with out them.
