Donny Shogun vs Ronin

[Jeffs55]

For those that are curious on my Uragan standard the Shogun is quieter than the Ronin. 25 caliber 34 grain pellet at unknown velocity. The Shogun is 7.2 ounces and the Ronin is 10.4 ounces. Also, the Shogun is quieter than the Sumo on this gun and on a FX Dream Tact.

ah, but is it just from the drivers seat or out in front of the muzzle to lol ...

Sometimes a larger moderator is not as quiet as a smaller one. My Tanto almost always out performs my Tatsu, except when I push more than about 50 fpe through it.

Shogun: 1.6" x 8", Volume: 16.08 in^3; 7.2 oz.
Ronin: 2" x 6.25"; Volume: 19.63 in^3; 8.5 oz.


It seems to me that a baffle system needs some "optimal" pressure to perform well. It is easy to push a little air through the thing but as the velocity of the air within the moderator increases the turbulance ramps up and "feeds" upon itself. An engineer would say that the turbulance increased in a non-linear manner. The harder you push the harder it gets do the pushing.

I think that is why we see this behavior. There is nothing wrong with EITHER of his offerings. Neither is superior but this one works best at one pressure level and that one works best at another.

Empirical data like this should include the caliber of the AG, the projectile and the muzzle velocity OR fpe. If enough people post enough of this sort of empirical data we will be able to infer from that what we want to know.

Just my two.

The sound level was difference was noted by myself and a witness. I shot the gun, the witness listened. The pellet fired was a 25 caliber 34 grain at unknown velocity. The gun was fired under an overhanging roof.

The 'overhanging roof' clarification is a good one. I have DonnyFL Ronin and an DonnyFL FX 'moderator upgrade' and despite the former having -- visually -- maybe 2x the volume of the latter, I almost can't hear a difference... when inside a concrete garage. Curious if there's be a more marked difference outside.

I am certainly interested. Thanks for this. S7

I undersand that there are apps on smart phones. Accuracy in the level isn't important but taking reading with out a Mod and then each one give an idea of what is actually happening.
