Subsonic 308

[NTXshooter]

Has anyone tried this ammo?  I have seen it at my LGS and on line.  I just wonder how it performs function and ballistic wise?  Is it an alternative to 300 blk?

I went to gunbot.net and looked for subsonic .308 ammo. One of the more interesting rounds is the -- a hunting round. It comes with a caution, that "these rounds will not cycle a semi-auto firearm." This may be a common issue with subsonics in .308, although I can say that subsonic .22lr cycles just fine in my Ruger 10/22. Also interesting is that a lot of these rounds consider themselves to be "match" ammo.

 

Here's the selection I found at gunbot:
