TT shroud, 6" vs 9"
Just ordered Talon-P, also going for a TT shroud but not sure which one, 6″ or 9″.
Obviously want the most effective though also want to keep to the packaging of the rig short and not too nose heavy. Willing to make a little sacrifice in attenuating performance to retain compactness, say half the report of an out of the box Marauder.
Will be shooting at higher power levels mostly, also getting the Quick Change Top Hat.
From those that have these shrouds how does the 6″ and 9″ on the Talon-P in particular, compare to say the Benji Marauder?
My limited experience, have spent some time recently shooting a .22″ Marauder side by side with my .22″AA S510, Marauder at 25ft/lbs, AA S510 at 30 ft/lbs, M-rod to my untrained ear sounded approx half the volume of the AA, the AA is too loud for how and where I use it, a Maruader is borderline. My .22 AA S200-B at 18 ft/lbs has a little CF shroud that brings its report down to very acceptable even inside barns while on Rat Safari.

Received the 9″ shroud, glad I went 9″, very light weight, nice conical baffles, aesthetically fits the AF nicely, and makes a BIG difference in the report. Thank you Tony, great work. 😎
There’s a lot of info on this under the bullpup topic “How to quiet an Edgun” and the efforts tried indicated vent holes about two inches up from the shroud did indeed help, but the problem is to stop there and go no further either in size or number of holes. The holes decrease the psi of the air being attenuated by the ldc baffles, and it does work. it’s not the end all answer, but in your case, it can make a definitive difference.
Remember, no more than six to eight, and 1/32″ diameter.

Hoot,
In wanting to reduce psi being attenuated to further reduce the audible “Phssst“, how far back from the shroud-to-Talon-P frame should I drill these holes? Noticed with the end cap removed when installing the shroud that the bushing supporting the barrel is vented.
Accurately sizing and placing the holes is not a problem, have a manually operated Bridgeport mill and lathe in my shop with DRO’s, (use mostly for custom cylinder head work and other small fabrication projects). 😉
Thanks in advance,
Paul
Thanks Panedemic and Hoot.
Pretty sure I’m going 9″
Interesting point on the holes at the base, noticed my AA S510 eXtra FAC has three .158″ dia holes around the base of its shroud that expel a small puff from the shot cycle, (sure wish it was a LOT quieter than it is).
Does the Talon-P have a barrel bushing like the other AF guns, if so would adding air ports, (holes) help relieve pressure pre-baffles to expel around the power wheel?
If you go 6″ and are not quite satisfied, you might consider six to eight small holes 1/32″ around the base of the shroud.

6″
The girls will always prefer the 9 inch over the 6!!! :winkn:
Although I might suggest the 6 then 9!!! :rofl:

Check the breech, note how much of the shroud is used to attach to the breech. Come up two inches for the holes. You just have to be certain to drill the shroud up enough to where there is nothing but the barrel inside. Don’t go nuts on the holes. This WILL help, but too large or too many holes will make noise by themselves. Keep them small and no more than a single row of six to eight. Works great!
