I love how people will try anything to discredit the 357, so people will look away from it and not accept it for use, especially the 357SIG. Its like they are scared of the 357SIG or something. Speer GDHP 125gr, I picked up a bunch of it when a local firearm store was closing a few years back. Range, I use a variety but all in 125gr.
Don't mean to stray for the topic but somethings need to be addressed. Even a 22lr fired in a room is loud, a 9mm fired in a room is loud, 38 Special...40SW...380ACP....a lady finger...etc all will be loud and you will have ringing in your ears. If this is the case that people use to not consider a cartridge, then they really do not have any idea about their firearms imo. Less noisy...its not like its going to be on t.v.
Hope this helps...
Here are some decibel levels (Notice no barrel lengths were give, that also plays a factor):
Table 3. CENTERFIRE PISTOL DATA
.25 ACP 155.0 dB
.32 LONG 152.4 dB
.32 ACP 153.5 dB
.380 157.7 dB
9mm 159.8 dB
.38 S&W 153.5 dB
.38 Spl 156.3 dB
.357 Magnum 164.3 dB
.41 Magnum 163.2 dB
.44 Spl 155.9 dB
.45 ACP 157.0 dB
.45 COLT 154.7 dB
Notice in the following links there will be slight difference in the numbers. That is probably because of where they were testing (size of the room, the rooms insulation, range, temp of the room, temp of etc etc), barrel lengths, and the cartridge itself i.e.: the gunpowder (and amount of) and bullet weight was their test cartridge. I'm sure they did not use the same gr and weight cartridge for every test. So I would say these are averages:

This was taken off another forum and has some good info on firearm decibel levels. (Notice no barrel lengths were give, that also plays a factor):
"Some common firearm loudness levels are:
22 rim fire rifle 126dB SPL
30/30 rifle 158dB SPL
12 gauge shotgun 3-inch magnum 157dB SPL
.357 magnum 164dB SPL
A whisper is approximately 20 dB, conversational voice is closer to 60 dB. A vacuum cleaner is on the order of 80 dB, a motorcycle approaches 115 dB. A fighter plane on take off roll cranks out about 140 dB, which is quiet compared a firearm enthusiast's environment. A 12 Gauge shotgun is a 156 dB wonder, as is a typical 40 S&W pistol. A 44 magnum is approximately 164 dB and all of those big ported rifles tip the scale at over 170 dB. The threshold for pain is 130 dB and hearing loss, trauma, occurs at 160 dB. Ear protection reduces the dB level that reaches our eardrums. A good set of ear muffs cut noise by 40 dB, which brings that big ported blaster down to 131 dB. Keep in mind the threshold for pain is 130 dB. Slip in a set of ear plugs under those mouse ears, and another 30 dB is clipped, getting down to a the soothing sound level of a chain saw..."
