Years ago I built a subsonic 308 on a Brno with a big Gunworks suppressor it must have had a 18-20" or so barrel.

With 210 VLDs & Trail boss it was indeed as quiet as a subsonic 22.

It weighed as much as my Rem 700 LSS 300 Rum & didn't kill as well

But it was heaps of fun..... Whish........THUMP

Edit...or did I use Trail Boss.... I did use Dacron filler...maybe it was before Trail Boss... can't remember...getting old....
