When I first bought a .357 back in 1983 -- and had only fired a .38 previously -- I took it to an old stone quarry to test it out.
I was completely ignorant about the differences in a .357 and .38 -- and didn't realize the quarry's stone walls would amplify the sound many times over.
I got educated really, really, really quickly -- and part of me still can't believe I was so naive at that point.
I took precaustions against ricochets, but couldn't have ever conceived of how loud the sound would be.
I fired 6 times as rapidly as possible -- and was immediately struck almost stone deaf.
In fact, I was deaf for nearly three weeks -- and terrified that my hearing would never recover.
Finally, after about a month and a half, it inched up bit by bit -- until two really large globs of wax worked out of both ears.
My hearing now is actually a little bit better than average for my age -- with only a tiny bit of high end loss.
However, my ear doctor said I was extremely lucky -- and apparently only the fact that I had a lot of compacted ear wax I didn't know about saved me.
Still, both of my ear drums are perforated -- and it's probably only a matter of time before they tear further.
I understand that ear doctors now have a bonding agent -- almost like super glue -- they can put on the perforation. That's one of my objectives soon -- to find out more about this repair.
I also understand the opening your mouth slightly when you shoot without hearing protection equalizes the pressure somewhat -- and may lessen the damage. Army range instructors used to teach this -- and it might just be an Old Sergeant's Tale.
Also, pretty strong research indicates having adequate magnesium levels in your body -- of all things -- seems to have some protective benefit to hearing against gunfire and other loud, sudden noises. Some 60 percent of us don't have even close to the right amount of magnesium.
I take Shaklee products -- and believe me, I make certain I get plenty of magnesium (which also seems to help prevent heart attacks.)
Nevertheless, even when hunting -- if I possibly can -- I have some form of hearing protection.
I'd never fire a .357 indoors -- ever -- after what I went through -- or a 10mm either.
Ironically, up to the point of my "enlightenment,"
I'd been highly protective of my hearing -- because my father lost most of his as an anti-aircraft gunner.
