So I've been trying to test and quantify as many different moderator designs as I can. You can see the results here:
https://www.airgunnation.com/topic/fx-crown-bespoke-moderator-tesla-gas-diode/page/5/#post-453278 One somewhat counter-intuitive thing I've discovered is that larger diameter tubes actually have a tendency to make sound attenuation more challenging in regard to cutting that initial peak or "uncorking sound." This appears to hold true, not just on my .22, but also on my big 80 foot pound .30 cal Crown.
Because of this effect though, the Tatsu might not be your best option for sound suppression. The Tatsu very likely would be out-performed by the Tanto on your gun as it is both longer and smaller diameter. If you're having clipping issues, it is very likely you have muzzle concentricity issues as well, so going with something even longer like the Koi or 0DB may solve one issue but create another.
As an aside, I've struggled mightily both to figure out why large diameter moderators tend to be louder, and to make one which is quieter. Thus far I've met with failure, to the extent where I'm not only losing what few hairs I have left over the subject, I'm starting to question my sanity. After all, how could a design so much physically larger not be as quiet as or quieter than an otherwise almost identical one of smaller diameter? I don't have the answers yet, but I just completed another round of testing today so hopefully I'm getting there..... *shrug* It really is a very strange problem.
Anyway I hope something in all that was useful. If you have any questions I'll do my best to answer them, but for now my best advice is to try a different mod because you may not have a setup well optimized for silence, particularly if you're putting that Tatsu on top of your gun's shroud.
