Has anyone with a 357 rattler tried an aftermarket moderator like the huma or donny fl? Does it make a difference?

I was told that they are making an adapter that will allow the use of aftermarket and should hit street in November.

I'm using a DonnyFL emperor with an AEA adaptor for M14 x 1 threads at the moment but cannot utilize the shroud. If an adaptor would allow the use of the shroud the emperor should be very effective.

I know it is not a Rattler, but I have a Sidewinder and I found swapping to practically any other appropriately sized moderator made a vast reduction in sound level over the stock moderator. I just don't find the design of the factory moderator to be particularly good, and I expect the Rattler mod is the same as the Sidewinder (basically a tube with holes in it and too many baffles too close together).

I've been using a Huma Mod 40 Compact on it, but it is sized for a .30 cal and the gun a .22. It is the best one of the batch I have tried on this gun, including a Donny FL Tatsu in .25 cal, a Huggett Mini-Magna in .25 cal, and a Buck Rail tapered in .25 cal (the Buck Rail was the loudest of the bunch, but still better than the stock one).
I have ordered a Huma Mod 40 Compact in .25 to try, and I plan to add one or two sections from my .30 cal version to it to see how quiet I can get it. If it works well, and I can tolerate the length, I might get an STO Sarrisa for it, but I'm trying hte Huma first.
In the end, there is only so much that I can do as the action on the Sidewinder itself is very loud - a good 10bB louder than my Huben when compared with a good iPhone app, measured about two feet away from the action with the muzzle buried in a pillow shooting without ammo. This gives me a view of just the sound from the action, and the Sidewinder this way is louder than the Huben firing an actual pellet. It's just an all around loud gun . . . . but it certainly is quieter with a better mod on it than it shipped with!
Did you get your Bullysyclone? I am interested in those if they work well.

Have you shot a rattler yet? Maybe removable cylinder/clip causing the loudness. My lcs sk-19 in .25 was very quiet shooting at 90fpe with stock mod. So your sidewinder is a .22?

I have a .30 Sidewinder as well. I tested a number of moderators, (Sumo, Ronin, Tatsu). The one that sounded the quietest to me-the Huggett Magna.

I have the sto extra high flow sarissa on my impact 357. It has the tensioned kit with no shroud at 170-175 fpe. The sto has replaced a ronin and is quite a bit quieter in my opinion.

Never tried a Sarissa (I should try one), I did try a Falx, it was just average. On my .357 Benjamin Bulldog, I use an Emperor with no extension and it works well, but my Bulldog has a mild tune of 120 fpe.

I bought the donnyFL adapter to put on the rattler but I have a rattler with a non threaded shroud. I had someone with a lathe machine the threads off the adapter so it would screw on to the barrel and fit in the shroud. And I needed an aluminum spacer on the barrel behind the shroud because there was a gap left over and the shroud slid around a bit.
Using the donnyFL emperor it seemed a bit quieter, if I use it with the expansion chamber it was a little bit quieter but not a lot. I think the Emperor does a better job than the factory shroud/moderator but I just used my ears, I need to do a decibel reading.

I just did a test on the back of my house with the ballistic gel for a target. Here are the results:
-DonnyFL Emperor: 120.4db
-Emperor plus expansion tube: 117.4db
-Factory mod and shroud: 117db
The winner is: Factory! The way it uses the shroud to help dissipate the air is a big advantage over using just a moderator. I just like being able to remove the mod to make the rifle shorter.

I just tried the rattler with the DonnyFL Yokozuna. It made 118.3db, 2.1db less than the Emporer. That's a very impressive drop considering the Yokozuna is smaller than the Emperor.
The only problem with the Yokozuna is mine takes an incredible amount of force to attach. And I need a strap wrench to remove the quick disconnect piece from the barrel threads. Other than that it is a very nice moderator.

It's 1.3db louder than stock, yes. The only benefit to being able to remove the moderator ive found so far is to make the rifle shorter. Earlier rattlers had a threaded moderator I guess that could be removed. Mine press fits into the shroud so it's non-removable. You can remove it but then the shroud will just fall off.
