The Quiet Corner

[AnimalHitman]

This thread is for all you stealth-conscious hunters out there; a sort of how low can you go? I'm interested in hunting rigs that present an extremely low audible profile.

I have a Daystate HP Pulsar .25 on her way from AOA, with a DonnyFL Emperor waiting to be screwed on. The fully-electronic platform of the Pulsar eliminates cocking noise and hammer smack, and the Emperor takes care of the business end. What other set-ups do y'all have that are uber-quiet?

 

[Hookster]

Leshiy going 780fps 22cal with Donny at the end is about as low I can go. Even beats my RedWolf on low power or damn close. Your Pulsar setup should be very quite especially if you keep it below 1010fps.

My marauder in 25. Hammer spring preload set at max, hammer stroke length set at min, and Valve metering screw damn near shut. 3200 psi fill, 140 shots from 320 to 250 FPS. Lays waste to sparrows at 20 yards like a ninja.

Reigaide with a rowin on it pretty quite 

 

[AnimalHitman]

Yes, Hookster; keeping it subsonic is critical to keeping noise down. Of course, I'll have to Chrony, but I'm looking at mid-800 fps.

 

[AnimalHitman]

Kay, hammer spring preload and hammer stroke length are two metrics that I had not considered. Thanks

 

[AnimalHitman]

Yes, Bob; moderating the business end makes the most difference!

Ok so I have a impact .25 with a Donnyfl shroud and originally it had a sumo on it. I was curious to see if I could get a quieter report. My impact tuned to shoot @ 840 fps the decibel meter reading from 10 feet in front of the barrel averaged 82db. with the sumo. I purchased a ronin and emperor. The ronin averaged 80db., the emperor averaged 78db. Note: the decibel meter I was using is a app. on my phone. So I tried messing with different materials used inside of the moderators, I was able to bring the db down another 5, funny thing is the ronin & emperor had the same average 72-73db. My neighbors only hear the pellet hitting the birds, which if you have been to Hawaii know the houses are built close to each other (no more room on the island) hope this helps.

Blunt force trauma!

What material did you use in Donny’s moderators to make them more quiet.

 

[Kaeokini]

What material did you use in Donny’s moderators to make them more quiet.

High density foam. 

 

[AnimalHitman]

Wow, Kae; you've put a lot of thought and effort into this! I thought I was obsessed with stealth! Is that foam the spray kind or wrap-around sheets? This is the aspect that really seals the deal for me with DonnyFL moderators. His highly-engineered design allows the user to disassemble the mod to do things such as experiment with various sound-absorbing/dissipating materials.

 

[archerhmr]

Kaeokini what thickness were you able to stuff in there. Did you hold in place with tape to be able to insert into housing.

I’m also interested in keeping the gun as quiet as possible. The Red Wolf .22, especially on low power, with the Hugget moderator is remarkably quiet. I do wonder if one of the Donny FLs would be significantly quieter than the Hugget?

 

[Hookster]

DHart, I tried a Donny KOI and due to it being oversized to 25cal it was louder than my 22cal Huggett. I still like DonnyFL mods though might get another model to try.

I've got a hatsan Bullboss .22 with a DonnyFL Ronin on it, I can hear the hammer spring and pellet hit the target. From about 10 feet away you can't here a thing .

 

[AnimalHitman]

Well, DHart; from all the reviews I've seen, DonnyFL outperforms Huggett (and everybody else). But, the aspect of DonnyFL's design that sets it a breed apart is that all the external components are CNC machine-threaded. There is no epoxy involved. His moderators can be easily disassembled for cleaning and felt replacement. His designs do not alter the host in any manner. DonnyFL has a wide assortment of adapters to accommodate virtually any make and model. If the proper adapter is not in his line, he will custom-make one. He is head and shoulders above his competitors.

 

[Kaeokini]

Kaeokini what thickness were you able to stuff in there. Did you hold in place with tape to be able to insert into housing.

1" thick, used the felt that came with donny's moderator and painters tape to hold the ends from moving. Gotta roll it carefully to fit.

It's the wraparound sheets. I got it off of Amazon. 1" thick 24X24. I so a YouTube video by ernest rowe I think that's how his name is spelled. I tried different types of felt also, plumber's felt worked really good also, steel wool extra fine 0000 not so much. I have to be like a ninja here at my house, my 75 year old neighbors grumble if I fart loudly.

Aloha, Kae! Ah, Hawaii; I spent a week there one night when I was in the Navy! I hear you guys are getting slammed with a hurricane, Are you affected? I live in SoCal; what is this thing called rain?
