DonnyFL Tatsu or Tanto?

[JonasW]

I have a .22 Crown that shoots at 36ft lb/50J. I have a internal mod in the shroud that works rather good, but I'm thinking about trying a real moderator.

Maximum length for the mod is about 5" for the gun to be easy to get in and out of the gunsafe. Has anyone compared those two against each other on a 30-35 ft lb gun?

I might get a longer one if there is a big difference in sound reduction AND if I can unscrew the mod between shooting sessions without a change in POI?

There will not be that big a difference in sound between the 2 models. I used the sumo , shogun, ronin , emperor and there was about 8 DB difference from smallest to largest.

Sound is on the logarithmic scale so 8db is about 80% louder. Sound "sharpness" is also a factor. That is generally a characteristic of the sound producing part but attenuation can vary by frequency for different devices.

For equal lengths, everything else being equal, the larger diameter will perform better because of it's additional volume. 

If your goal is to keep your gun's length to a minimum, always go for the fattest version in the line that will fit.

I think the Tatsu wins. Short and very effective. I have a .25 Tatsu on my Ataman M2R .25 that quiets the rifle down to a hammer strike followed by a pellet strike which even hitting a cardboard box is louder than anything else in the equation.

I have a hard time deciding. The Tanto follows the shroud nicely with the slimmer diameter. The Tatsu is shorter but won't look as slim.

The Tatsu should be the better one regarding sound because of the higher internal volume.

Does anyone have a picture of the Tatsu on their rifle?

Thanks!

Here's the tanto

I have a .22 full size Raptor shooting 18gr @ 950fps with the Tatsu and the Tatsu’s report makes it very back yard friendly.

How about the FX DonnyFL 1.38” x 5”? Right between the Tatsu and Tanto. 

 

[JonasW]

They only seem to be sold in the US. Can't find it here in Europe.

@nalby Do you notice any difference in sound between the Tatsu & Tanto?



When I see the pictures above with the Tatsu on a rifle with a moderator, it doesn't look so fat after all.

I personally can't tell the difference between the two , they are both quiet. I use the tanto on my pistols and the tatsu on the dreamline, I tried them both on the dreamline shooting 850fps and my impact shooting 950fps and they both did a great job

The slimmer diameter was one of the reason I went with the Tanto. My Bantam doesn’t need it, but it really quiets the bark of my Compatto. Pellets hitting the target are the loudest noise. Pic is of my Bantam with Tanto attached.

Thank you for all the answers and pictures. I decided to go for a Tanto.
Now I just have to see if the authorities (the police) will give me the permit for it...
