I've got two guns that I've shortened the barrels. Using adapters to install the silencers.
To go with that, I'm using the DonnyFL, Tatsu silencers on both. Why, because they are short.
The last coupla days, I've been playing with the sound deadening material in one of them. Paper, Scotch Brite (two grades) and open cell foam, so far.
In the very many years that I've worked in the Aerospace industry, Foam blocks are attached to the walls and ceilings and much of the floor in all of the acoustic test cells that I've ever be in. Very similar to what used in recording studios. Just large triangular blocks of open cell foam.
I found some foam sheeting use as a packing filler. A semi-closed cell foam does a decent job of quieting the bark. I used my .22 Walther Reign as the test rifle. The testing was done in my short "range", which is near the hall down the center of my house. The gun was filled with air. The foam filled Tatsu, was audibly quieter than the unmodified Tatsu. The sound was also of a lower pitch than the unmodified Tatsu. I thought cool, the short tube of the Tatsu, with better quieting of the sound emitted.
THEN...today, I tried the same two Tatsu silencers on my .22 Prophet. I didn't grab a particular one first, just grabbed one to see if I could tell the difference. Ha...the "Unmodified" Tatsu did much better on the Prophet than the foam filled Tatsu. Just the opposite of that on the Reign..!? And to add to that, the regulator on my Prophet has been turned way down by the person that did some tuning work on it, so...I figured that if anything, it should be about the same as the sound emitted from the Walther Reign...but not so. The unmodified Tatsu on the Prophet is "much" quieter than I ever thought that it would be. The shrouded barrel combined with the original Tatsu is the quietest PCP that I own (9) by far.
So, as something that I've always been known to do...experiment, you might find things that you didn't expect...and have some fun doing it.
