20 Silencer Test

[mrbulk]

Well, Charlie, 😊
when I go shooting, I get so intense, I forget about pretty much everything else.

For example, I spent all night fixing and prepping gear, slept two hours, and then went for a full day of shooting, actually 100 yard slug testing.I was sitting on 4 inches of dried cow dung, hunched over my shooting table that's 6" too low for me.
And I was out in the tropical sun all day.
I hardly ate or drank anything!
I didn't rest.
I think I went to the bathroom just once on that "cow range".

I was so burned up, so dehydrated, the stomach empty — but I didn't even feel it!! 
(Well, the next day I sure did.... 🤣).
Yeah, I call it FOCUS. My wife might call it crazy. 


So, filming, pictures, and stuff really requires a lot of divided attention from me.... That's hard — since I'm so FOCUSSED.... 😄

➔
🔶 I've been drooling over a Tactacam with the FTS scope mount, because that's just a button press and done. Easy peasy, even when I'm FOCUSSED.
But the price is just far out of reach. 


So, yeah, I should go through my shooting notes and see if there's anything worth telling....! 😄

Okay okay okay, we'll just take your best written stories from your memories and notes...

Gents,

I'm supposed to be in bed, resting up for a day* of shooting.
But here you keep prodding me and keeping me awake....!

And the fool I am keep reading, and responding. 🤦🏻‍♂️


So, yeah, maybe some airgunner want to come down here to Peru for a vacation!  (yeah, you'll have some camera duties, too....! 😄

But Peru is — when the corona craze is over — an incredibly beautiful country:

▪20,000 foot mountains
▪Tropical jungle (think National Geographica), including sweetwater dolphins

▪Clean and beautiful beeches, some with black sand (warm weather when the US shudders under sub-zero's)

▪Macchu Picchu — the Inca settlement everyone should have seen before they die
▪The Nazca Lines, mysterious lines engraved in hardened sand — several hundred yards wide — half a millennium before they invented planes and drones — How in the world did they do that, and why??

▪Deserts, rocky hills, almost right behind my house
▪Islands with sea lions, seals, and penguins
▪The food, oh the food, Peruvians can cook like no other nation that I have visited so far.



OK, I'll stop here. Visiting Peru is an adventure, not a 5-star tourist tour.



OK, enough, I'll turn this screen off, NOW! And maybe I'll have a story to tell after tomorrows shoot. 😊

*(yes, I worked both weekend days full, tomorrow is my day off...)


PS:
I have succeeded to thoroughly derail Charlie's thread. 😟  Sorry, man.
But..., you pushed my buttons! 
And so I pushed the keys..... 😄
NOW BACK TO THE SILENCER TOPIC!!

I just tuned a PP700 with the HST from 12FPE to 14.5FPE — and with my ears I could not perceive a difference in loudness.

I'm using the smaller one on the pp-700 now does a fine job! It was given to me by an LE friend. 

[Cableaddict]

I have received several more silencers (or suppressors, moderators, LDCs, pickles, front-ends or whatever you want to call’em) so it seemed like a good time to do another sound output comparison test.

I wonder if an actual pickle would work?   Plus, you know, if you're out hunting and you get hungry....   

---------------------


But seriously,  I see you tested the lower-end silencers from Wolf,  but has anyone tested their high-end units?  Evidently those use something called a "K baffle," as opposed to the more common conical baffles. It is implied that this shape works better.   

I'm quite interested to know if it's true.

Allan, I am unsure because I have never shot one to my knowledge, there may be key baffles in some of the units tested before, but most of them are unable to be opened up, the makers wanting to keep their internals proprietary. I bought the two wolf silencers because of their better pricing, the K-baffle units are all well over $100.

[mrbulk]

But based on the latest tests of some units I have in my possession now and will eventually be posting about, the best sound reduction results seem to come from units that are designed asymmetrically inside. Without going into further detail, it’s just that they are designed to break up and further occupy the air blast within the unit while giving time for the pellet to exit first, and then to release the rest of the air blast in a slower, more controlled rate out the front. The uneven, unequal, asymmetrical internal designs of those types of units appear to be superior.

Unsure how the mods would react to this video but I now have one incoming, should be interesting to see the test results...

Great, and I just ordered one of the old designs? Maybe I should’ve waited a bit and you would have a better, more efficient one.

Haw! No worries Rich, according to the makers the AUO has been designed to use the main housing as a permanent test chassis. Any new development of the internals, if/when one is created, would be a direct drop-in replacement at significantly less cost than the all-metal machined housing you would already have.

I found this engineering video on youtube, which might explain some things.

Yes Stephen thanks, a version of the Tesla valve (or diode) is used in the STO Falx, for test results please refer to the dB readings in the OP above.

If cost is not an issue,  what is the one silencer you would recommend? The only stipulation is I can use it on multiple guns.

If cost is not an issue,  what is the one silencer you would recommend? The only stipulation is I can use it on multiple guns.

Man, I would love to be able to publicly recommend certain ones, but not only might that put a damper on any new ones volunteered for tests (there have been units offered for test already in the past, and there are now a couple of new units to be included in the next comparison), but also please recall that the testing regimen uses only one gun, on one day, under one set of conditions.

So like if you had a 50fpe gun for example, the Neil Clague I have was built specifically for that exact level of power and likely would perform best on it, but many if not most of the smaller units might do worse, and perhaps even fail structurally.

But the guns that were (and will be) used are the AV Avenger .22, Evanix AR6K .22 and FX Wildcat Mk3 .22 which, in their states of tune, all average more along the medium range of power for most PCPs (up to 30fpe), so the results you see in the OP would represent .22 guns with that average level of power, and hopefully cover the most useful range of guns for the majority of people.

If the guns used were different, like a high fpe model, or a CO2 gun, or a springer, etc., then results would certainly be different.

In other words the best recommendation I could make would be to take the results and figure which one most closely suits you based on purpose, looks, budget (oh yeah, cost was no issue), size and the intended gun itself.

Subjectively, I myself do like certain ones better because of perceived value, or cooler looks, or easier handling (spinning on/off, grip, texture, etc.), or overall size vs dB, accessibility, etc., but then someone else might prefer different units based on these same parameters.

So to sum up, I just report (and actually have a heck of a good time doing it!).

Now that we have the official answer, I feel free to be a little facetious:

If cost were no object, I would buy 20 acres of land with a natural backstop on the north end, so I can shoot from the south; to see clearly without glare .  That should work to quieten anything I care to shoot.

Get the AUO for $65 shipped (got mine in 2 days, seriously) to your door.

All aluminum except for the 3D- printed monocore internal.
