    Very pleased with the Ronin on the Benjamin Bulldog….big reduction in the bark. I bought a db meter because I had to quantify the difference. I include a .22 Ruger Charger (10" BRL no suppression) for comparison as they're similar in loudness.  These are averages of 5 shots at each distance.  The 5' and 25'  positions are at a 90 degree angle away from the shooter even with the muzzle. The 60' is directly in front and the 20' directly behind the shooter.  Simply trying to get a feel for what was happening around me.  Your mileage may vary.  =)

    20'       95.1              89.9             103.2                       94.2


    Not bad when considering a center fire PB is 160+ db. 





    I just put a Donnyfl Ronin on my FX Impact X .30cal with 700mm barrel

    As stock I was getting reading of 92-93db with the Fx LDC.  Using a Iphone app for readings

    I put the Ronin and and was getting reading 90ish.  Not really the sounds reduction I was hoping for.  

    So I started experimenting with the core wraps.  I tried some open cell foam…no change.

    I tried the material below, it is called spacer mesh.  I did a full wrap and readings dropped to 89ish.

    Hmm….my thought was the material wrap, felt, foam, and spacer mesh, is not allowing complete use of the volume of the cylinder.  I also figure that there is little cancellation of pressure waves in the cylinder because of the full wrap.

    So I tried the spacer mesh as show below.  I am guessing that this causes three pressure waves in the cylinder and they "run into each other" and cause some cancellation of the waves.  As show I am getting readings in the mid 84db.  All readings taken next to the rifle on the bench.  Rifle is shooting at full power.
