I have an 8” upper I’m thinking about getting a suppressor for. I’ve read mixed reviews with several people saying it’s not worth it to suppress because there’s still a lot of noise through the action. I don’t have one to shoot before buying. Anybody have experience with this? | ||

Absolutely, but to get the most benefit, you should use subsonic ammo (velocity slower than 1100 feet per second, give or take depending on your altitude). A suppressor will quieten the sound of the powder detonation of the cartridge inside the barrel, but won't soften the mini-sonic boom of the round that's traveling through the air. So you will get the most benefit from using subsonic ammo. Firing supersonic ammo through a suppressor (in my experience) will be softer than without a suppressor, but still won't be quiet, and certainly not hearing-safe. Some say that 300BO still won't be hearing safe using subsonic with a suppressor, but that's subjective. Plus, you can always apply for a tax stamp and then convert your pistol to a Short-Barreled Rifle (SBR) once you have approval. Phone's ringing, Dude. | |||

Even on 9mm guns running subsonic ammo, the action noise is loud at the ear. I can't imagine thinking it isn't worth it to suppress a gun because the action is still loud, I wouldn't pay any attention to those people. ______________________________________________ Carthago delenda est | |||

My SBR started out as a PSA Jakl pistol with an 8.5" barrel and after getting it stamped, I shot subsonic and supers using a Dead Air "Sandman K" suppressor. It's very quiet and a pleasure to shoot.

There is lots of available data about this question. But in general you are going to see approximately an 8-10 dba reduction at your ear (depends on gun/ammo/etc.). And since noise measurements are log that's a huge reduction in noise. huge. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

It makes shooting the weapon indoors a heck of a lot more pleasant. Supersonics are still loud but tolerable. Subsonics are stupid quiet, but I haven't found a combination of spring and buffer that will reliably run subs in my rifle that I'm also comfortable with on supers. | |||

For real? |
I keep my 8" 300blk sbr and sandman-k with supersonic ammo at work to put deer down with. quiet enough to not disturb the neighborhood (i work nights) I'm still waiting to get the okay to order the flow 556k for our work rifles. Not minority enough! | |||

I presume these put downs are all at close range and injured or trapped animals. Why wouldn't you use subsonic ammo? and cut the noise even more? “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

Sandman S on my Noveske Chainsaw 300 which is a 10.5” barrel. With subsonics all I can hear is the bolt cycling. | |||

Although not directly related to the original question, but still as a matter of possible interest to suppressor users, the speed of sound is affected primarily by air temperature, not altitude. The reason altitude is sometimes cited as a factor affecting speed of sound may be because the data is using the “standard” temperature for the elevation above sea level. For example, the standard air temperature for 10,000 feet where I live is 23.3 °F. Average temperatures here are much cooler than at sea level and the same latitude, but we don’t see 23° except in the winter. When I was using my can today the temperature was in the low 60s. There is at least one study showing that altitude can evidently affect the speed of sound, but the elevation must be very high. If we travel from sea level to the mountains there will probably be some change in the speed of sound, but because the temperature will probably change, not because of the altitude difference per se. ► 6.4/93.6 ___________ “We are Americans ….

For self defense, it would certainly save your ears if you had to shoot inside of your house. ______________________________________________________________ Common sense is no longer simply uncommon. It is rare these days. | |||

I believe speed of sound is dependent on the density of the medium, air with varying amounts of water vapor in this case. So it would be a function of temperature, barometric pressure (elevation), and humidity - all of them. ______________________________________________________________ Common sense is no longer simply uncommon.

Last chance, Nick. I'll have a response from you, or you're gone. Speak up or you're gone. https://sigforum.com/eve/forum...220033115#5220033115 | |||
