Donny has a combo Ronin tube plus Emperor, that you screw together. It makes for a LONNGGGG presentation, kinda hilarious, but it does seem to work. I can't tell whether mine works better on my power-tuned .25 than just the Emperor alone, because with the Emperor I just hear the ping by my ear from the bullpup, and then the loud THWACK! when I hit a squirrel or a tree/other hard background.
So that's the thing -- it may not be about the moderator entirely. Just hitting a target can create a lot of noise. If it does with my .25, I don't see why you wouldn't have the same problem but worse with a .35.
If I recall correctly, the edgunleshiy channel shows him using his "dirty 30" tuned down low and still getting away with it in a close-ish suburban setting. But that's the thing, his is tuned way down. And it's still not a .35, it's a .30. I'm thinking that moderator or no, you still need to lessen the sound of impact, and that will come from tuning your gun to a lower power profile.
And I'd still agree with another commenter here -- .35 in close quarters with other people sounds kinda scary. What happens if you get a weird ricochet or flyer or pass-through? I mean, people are killing adult hogs with .35's. Maybe instead of trying to cram a square peg into a round hole, you'd be better off getting something a little safer for your situation?
