I'm sure the powder is proprietary but I wanted ask does anyone happens to know what powder they are using in there GMM for the 308?

This may have been discussed numerous times and I apologize in advance as I don't have a search function using tapatalk.

From what I've read and heard, factory ammunition generally does not use any powder sold to the public. It seems to be the case with FGMM.

But this is just hearsay. Someone more experienced will probably chime in.
