Loud suppressors
- Thread starter mavracer

Trying to learn from this thread. Would smaller, shorter, lighter usually affect how loud it's going to be?
Yes to all. Silencers are a function of volume (and baffles). More and bigger are better - if you also want quieter too.
Yes volume is the biggest factor in how quiet a can will be.

It depends.
Weight is a function of more than just size. Materials and construction will be the primary indicators there. I build 1.6x9" magnum rifle suppressors from titanium that weigh only 10.2 ounces, and they are much quieter than something like the 1.625 x 8.5", 28 ounce monocore type legacy YHM Phantom 7.62
With volume, also depends. As another example, our .75 x 5.5" Salamander has an unpopulated tube volume of 2.0 cubic inches, and is quieter than our 1 x 3.5" Ocelot micro with a 2.3 cubic inch tube volume. And both are quieter than a number of "full size" 1 x 5.5"-6" rimfire cans with more volume but inefficient cores.
Which brings us to length; assuming similar core efficiency, it is going to be the biggest factor in muzzle end suppression. This is due the the time component.
Then there is the matter of host weapon. With autoloading firearms, the suppressors putting down the best muzzle end numbers often perform poorly at the shooter's ear due to high back pressure increasing residual bore pressure and bolt velocity, thus more noise coming out of the ejection port.
There are just a lot of variables that preclude generalities. About the only one that will consistently hold true is that the shorter version of the same can will be louder.

I have referred to this can several times within this thread and yes it is my loudest (by my ear), heaviest, actually has the greatest POI shift. (which isn't very much, it's consistently is only a inch low, the other (2) are either none or around 1/4")
Huntertown Kestrel 9
Supported Calibers: 9mm, .308, 300 Blackout, 7.62x39
Minimum barrel length 11.5 inches
Overall Length: 7.5 inches
Diameter: 1.5 inches
Weight: 21 ounces (includes mount)
Core Material: Stainless Steel
Tube Material: Titanium
Registered Part Material: Stainless Steel
(the manufacturer is sadly no longer "engaged in the business")
Now with the volume which I'm actually a fan of, (I also know that the baffles play a huge part) this can should be quieter maybe. I addressed the cons that I find, but I still use it. Now could I get it to be quieter ,, Sure I could shoot it wet or send it to someone such as MachIV shooter( I mention him because he is on this forum and can weigh in) to be either be re cored / or existing M baffle clipped and / or mouse holes drilled How much improvement the results would greatly vary I would expect, and not sure anyone would say. Is it a bad can ? some would say yes some no. I'm in the no crowd, I was warned that it was not as quiet as some of the other cans I bought from my dealer from the start (expectations managed).
I had my reasons for obtaining it as such I don't have buyers remorse. If I was to have a baffle or end cap strike this is the can I would prefer it to be in. Because none of the baffle are close enough to send a bullet into the registered section thus would be easier to repair than some of my others.

An(nother) excellent, informative Thread, Guys & Gals! Good Job! 
=====================
Last month I received approval for my first suppressor. It is a small "economy" model (~$255 onsale last June, IIRC) made by WMT (Witt Machine & Tool Company), the "Big Body Tu-Tu-Three Ultra Compact Suppressor".
I have only tested it a wee bit with two of my ARs (setup for the tests with 16" barrels using S'thAfrican 5.56 55gr M193-esque milsurp). It manages to remove the vicious painful edge from the sound, but some earpro will definitely be required.
I first tried it on my back patio and, after squeezing off the first shot, turned to look back where the cats had been sitting (~40-50' behind me). They looked alarmed but were still sitting there ... until further shots.
With the ~$14 shipping, the whole deal cost me about $620, total.
O'course, I now have a new, fun aspect to my hobby, testing assorted barrel lengths and loads ... and I can do this with light(er)weight,
unobtrusive(er
) earpro.
=====================
Reminds me of a time in the latter half of the '70s when a nice fellow at Atlantic & Pacific Arms (IIRC) in VaB was trying to talk me into buying a .45acp Ingram SMG plus its special made-for-the-Ingram Suppressor; only $250 apiece ... plus $400 bucks for 2 tax stamps ... plus a long wait for ATF Approval ... plus ...
Believe it or not, the main thing that kept me from getting it was, primarily, the burden of feeding it (I was also concerned with how to properly secure the things, 24/7).
I have since read that that odd-looking Suppressor is unnaturally QUIET.

I've looked at those before, I would guess it's very close in sound to my Torrent can.
I've got one of their SME muzzle devices on my 14.5" 450 Bushmaster. It's one of the better non NFA muzzle devices for directing blast away from the shooters ear.

Actually those Suppressor do run well , IIRC used spring in conjunction with baffles (hopefully I have not confused designs)
