121 db reading w/suppressor & subsonic loads

[Pitt300]

I was at the Silencer shoot yesterday in Longview, Texas & John Titsworth from Silencer Research was there w/his meter along w/Al Paulson.
We were shooting pretty fast & I did not see all of the readings & it wasn't totally scientific as we took NO readings w/o suppressors to see what the total reduction was.
John will be posting the results on his web site in the near future.
I was shooting 220g SMKs @ about 1020fps w/an AAC 7.62SD & I think most of the readings were around 121 db.
THAT'S quiet & they all cycled fine as I fired as quickly as John could reset his meter.

Super - Sorry I couldn't get over there, did you take any pictures?

[Pitt300]

All photos/videos that I've seen were on the Full Auto line.

That is really quiet, especially with such a powerful subsonic load! Do you know if there was any FRP?

[Pitt300]

John Titsworth will be posting all the results later on his web site.
There were a LOT of cans there on different hosts.
I fired 3 supersonic rounds before the 10 subsonics but I did not see all of the results so the frp will be reflected in the 1st supersonic round when he posts it.

That is quiet and N110 is good stuff. Sounds like a fun gathering. I dug out the list of sound signatures that Paulson had compiled and 121db is right there between 5 - 10 pumps on a Crosman air pistol :smile:.
