Calling all .357 sig fans!!

The threshold for pain is 130db. The threshold for damage is about 85db.

Also, the affect of double protection is not simple addition. In other words, a pair of 32db NRR plugs paired with 35db NRR muffs is not equal to a NRR of 67.

There are complex reasons for this but one simple one is that some sound reaches your ear drums THROUGH YOUR HEAD, which means no matter how much you plug your ear canals, you aren't stopping that sound at all.

The point about the noise level similarities between cartridges is spot on. It's like asking, "Which one will make me a little deaf, deaf or a lot deaf?". They'll all deafen you indoors without protection. Frankly, even WITH protection you're doing damage indoors. One cartridge versus another is a distinction without a difference.

Sorry, guys, but you are merely quoting links without completely understanding (or reading) all of what they're saying.

For example, a 3db increase yields nearly double the accoustic energy. There is a 7.3db difference between .357 mag and .45 ACP.

It's natural for someone to look at the difference between those numbers and think the sound levels are really similar. They are not. Not even remotely close.

I'm glad you pointed this out, it's a common misconception. From what I've read, doubling up (which I always do as a habit) will yield an additional 3-4 db or so. It's not a lot but it does make a difference.
 
I am a recent .357 SIG owner. I just got a caliber conversion for my 9mm stainless SIG 226. I got it in .357 SIG and then got another barrel in .40 S&W. It seems fairly accurate in .40 S&W, but it is super accurate in .357 SIG.

I have also gotten the dies, etc. for my Dillon 550 to load both. I have loaded the first batch of .357 SIG using a 125 gr. FMJ FP bullet and Longshot powder. It seems to be fine. If the manufacturer’s charts are to be believed, it is a pretty mild load producing pretty good velocity.

It's a distinction without a difference. Once it's loud enough to destroy your hearing, it destroys your hearing. All those sounds are so ungodly load, especially with indoor reflections and whatnot, that they WILL wreck your ears.

Yes, some are louder than others. Logarithms not withstanding, deaf is deaf. A handgun fired indoors without protection is plenty loud enough to wreck your ears.

I don't think too many deaf guys are going to sit around with a Log scale arguing over who is exponentially more deaf than the other.
 
I have been around loud noise a lot due to being a construction worker and will say that doubling up does work. Detonations, backfires, nail guns shooting through steel beams, generators and vehicles without mufflers, blow offs, jack hammers, cut off saws, rock crushers and the list keeps going on. Some of these may be as quick as a gun shot and others maybe a long steady noise. Now whether or not doubling up is as much as the first guy said where it adds to the protection, or its a few levels of protection said by the other person. All I know is that in real life the double protection works. No one was talking about a long steady concentrated directed sound amplifier creating vibrations in the body. Someone said / complained about "If you shoot that indoors without hearing protection, you will lose your hearing. That is why I dont carry .357 anything." and I offered up ratings, OSHA specs, doctors opinions and other sites discussing this. Choosing a firearm or cartridge by how loud of a sound it makes, makes no sense for self defense. Choosing on its performance, accuracy, and ballistics I can see, but sound. In the end they are all loud without protection. peetzakilla pretty much summed it up. Anyways, to each their own on this one I guess. Have fun.
 
I would never shoot my 229 sport as a self defense gun. With the comp it is exceptionally loud. For that reason, SD ammo is not that important.

Think about that loud in a confined space. You may say that you would rather be deaf the rest of your life and alive, but I would rather be both and have recognized the wisdom of less intense solutions like the 45 ACP or even the 10mm with the right loads.

I could not agree more. My HD handgun normally is chambered in .45 ACP standard pressure, either from a revolver or pistol. I figure this caliber has more than sufficient stopping power, but it won't penetrate through the house into where an innocent person may be within its path. I can't say that with my 357 SIG guns. As much as I love my SIG 239 and SIG 226 in 357 SIG, they are better used outdoors.
 
Cool thoughts everyone its funny how threads evolve it starts out as someone wanting to know what .357sig sd round people carry and it ends up as a disscusion on how loud certain rounds are.
 
What's In A Name?

I wonder if the .357 Sig had been named the 9mm Sig (which is more
accurate) would there be as many detractors.
