Bullysyclone Wylie Kanz moderators... throw everything else in the trash.

Even a lousy iPhone has an app, I bought a cheapie off of Amazon that works well. Mfg's aren't going to give a number because they can get their butts handed to them, all guns are different. I've posted comparisons of 4 different mods with numbers, it's not all that hard to do. As for why did I buy some, because I made the mistake of listening to some people that said they worked, without some actual numbers, I've got one that made my gun louder, not the desired effect.
None of the apps work well. Just like the fx chrono graph , it doesn't really work well. If you aim the rifle down, youll get a different reading than if you shoot straight ahead, both with the chrono attached.

Your numbers might not be accurate... or remotely close... a real decibel meter is the only way. I dont shoot my mouth off here and lie, my buyer/seller feedback alone would reflect that lol.

Either way, at some point, and hopefully soon I will try and take some quality videos to show my findings. Until then, happy shooting :)

If you're telling me this brought your EVOL down to a whisper I am intrigued.

I'm curious about the threading you used to attach the moderator to the EVOL. It doesn't look like a DonnyFL adapter and I can see there is something between the moderator and the shroud. Did that come with the moderator or purchased elsewhere?
That is an @Bullysyclone moderator adapter that I got when I got the moderator pictured. @madeintheuk also got one of these adapters, I shipped it to him yesterday, he should be receiving it today. The adapter and moderator worked wonders on my HPS, shortened the rifle and made it backyard friendly, I am hoping this weekend to take videos on both the Mini, and the HPS using all 3 moderators and compare it to a 0db I have as well.

Thanks for the reply. I look forward to your results, even if the pop sounds will be attenuated on a phone recording.

FYI - for an iPhone app that I've found to be reliable to db measurements check out 'db Meter Pro'. Everyone measures sounds differently so details on placement of the sound measuring device is important. But more important, I feel, is just seeing the differences measured at the same spot between the different setups. Then there is the tone of the shot each moderator produces which is a much more personal thing. I do agree with your assessment of the 0db - I find they are louder than anything else I use.
 
Seriously? Throw everything else in the trash. Is this an advertisement "As seen on TV.", which is never exactly what it is made out to be. Ten times quieter, not likely.
Real numbers with real scientific evidence will determine.


Yep, throw em all in the trash, or sell them, or take the words however you please.

I sold off all my other mods today, well except one, but it is for sale. :)

I trust what he says. He shoots almost every day. If he says it’s that quiet. IT IS!!
 
I would take words with a pinch of salt until proven otherwise. Ridiculous.
Ridiculous is your baseless comments. He said he’s going to make videos to prove it, yet you still have to puff your chest. Trolling seems to be a strong point for some.
 
What ctairgunner never really mentioned is that he bought the Wylie and while he is my friend his is not like other people that want free poop just to promote the item! I have plenty of these out there and anyone that has one would be more than happy to talk to anyone on how well these work and how well made they are! If anyone has Facebook they can look up Bully Racing and see what I do.

No I don't have a website because I can't keep up as it is....it's just me and some very nice machines. This airgun stuff is for fun and I don't make a living building this stuff, I just love machining and building the Best of the best!

And I'll pay for another, and another, which i plan on doing. I appreciate fine things especially fine craftsmanship furthermore especially fine craftsmanship from someone who is in the same hobby as I am for the enjoyment.

there's a couple iPhone apps I use to "listen" to the report of a moderator. Certainly not high-end or scientific, but both are capable of providing reference points.

All you need to do is mount the airgun on a tripod and set the iPhone on a tripod with a iPhone holder..5-10ft out and to the side..and away from any sound reflecting thing like the side of a house or a wall/fence..and record the relative numbers. Again..not probably the "actual" dBs..but a reference for comparison.

Sound Level and Decibel..both were free or nearly so..and work acceptably.

Just sayin'

--duc duc going--

Using the logarithmic decibel scale, if a sound is 80 decibels, and we add another 10 decibels, the sound will be ten times more intense, and will seem about twice as loud to our ears

You can measure sounds in dBA yourself with a sound level meter, such as this app made by the National Institute for Occupational Safety and Health. The app can measure sounds from 0 dBA (sounds so quiet you can barely hear them) to whispering (30 dBA), normal conversation (60-70 dBA), and even a jet taking off (140 dBA). Just remember to turn down the volume, move away from the noise, or wear hearing protectors, especially when the sound level is at or about 85 dBA!

It matters not if they work 'well'. but my iPhone and my cheap arse meter were very close to each other, the key is to use the same thing to compare, a dB drop or rise is just that, whether or not it's that particular level. As for the Fx Chrono, it works fine if you understand the radiation pattern of the unit but that has nothing to do with sound.

just the comment that i, we, should toss out all of the LDC's we have collected is nutz
have LDC's come a long way, sure everyone and their uncle have been making them
back in the day there were few off the self
i bought a Paris-D years ago, why so i could test my own, who remembers the Paris-D CNC machined gut
Donny-FL has made some of the best
Neil C. used to make some of the best
Weihrauch makes a damn good one for little money
and the fact you cannot buy a cheap sound meter for comparison testing is mind boggling 20 bucks
those LDC's look very nice and are well made i assume and maybe the best that have been made but all of mine will stay put and be used when needed

Really nice work. $179 per is a bit steep... It does look like the work is probably worth it. But I got to be honest with you I don't have a gun in my stable that needs a $200 moderator. So I think I'll keep mine.

I like the idea of mixing aluminum and carbon fiber. And I'll bet if it's only 003 over caliber it's pretty damn quiet.

Now about measuring decibels. You can get an app for your phone. Set the phone about 10 or 15 ft from the muzzle and take measurements from one moderator three or four and then three or four from the next moderator and average them. You'll have a pretty good idea of how much gain or loss in performance you have.

No it won't be as good as if you had $100,000 worth of audio equipment and anechoic chamber but it will certainly be good enough to give everybody an idea.

The reason that vendors don't give you a number is because they can't control how you test. Your number is unlikely to be the same as their number. Basically comparisons are only realistic when both moderators are tested on the same gun on the same day with the same conditions at the same distance from the muzzle.
 
Certainly scientific facts are (tho sometimes not to the ear, you can measure Hi-FI distortion you will never hear) the facts, but.
Personally I believe it would have to be better than the a fore mention mass import Chinese mod's that were so popular.
".003 over" is a GOOD thing. Fpe being equal the old 16mm AA shroud is quiter than a Marauder (or the new larger AA shroud) and the baffle tollerence is the difference.
Even up to a 80fpe .22 even a strict volumetric (everyone remembers them) With tight tolerance works. Well know before shrouds and people wanting to attach things to them.
.003 , less if possible on an air stripper inside a shroud would quite most shrouded airguns as well or better than a "1 size up" mod. When the shrouded Theoben Vanquish came out it had only a few inch's dead space in front of the shroud support(?) and I believe we have a member who owns one but with a true airstripper inside with .003- over bore size, pretty much AZ quite. Everyone familiar with Alan's used tolerances? They work. I had a 50fpe Bowkett custom .22 with an "empty can" about 6" llong with exit .002 over, silent.
If more people were strict utilitarians you might get the price down slightly (but not greatly) but QC shown and todays market, seems a deal.

Cant wait to not hear more.

just love machining and building the Best of the best!
Might be the best of the best, I'd like to see one run side by side against some of the better ones, tested for accuracy and for quieting with dB meter.

Your machining is very nice. If you're holding your bore .003 over caliber. That's pretty tight. What do you think your run out is over 150 mm?

I am pretty aware as to why no manufacturers give a number,

As well as aware that there are many, many apps out there.

I also am aware that many discussions happen on this board and things are taken for gospel without any proof had when it runs with support for "their" favorite vendor.

@lbc_PSI thank you for posting a suggestion to an app instead of just being a Ms Trunchbull. Also for your lack of pitch fork and torch reply. 😀

Every single thing said here!! Spot on. Donny moderators are trash in my opinion and the fact people will spend $150 on them while they're made for "$1" blows my mind.

The underlined and bold portion in your post nailed it on the head.

Now , to everyone posting so angrily , if daystate or fx posted this. You'd probably not questioned it 😀.

Some are only in this thread to puff their chest up after other matters that happened outside this thread as well, which is silly.

I will succumb to the pitch forks and torches and supply some sort of evidence when I can, as I've said a couple/few times now.

Stay salty everyone, and remember, throw all the inferior moderators in the trash 😀
