No idea if the OP is still around, but just an update on this ammo: seems like a 175 SMK in Norma brass.
It's very slow: 2600 fps in a 26", 2530 fps in a 20"
In my 26" rifle it's a legit replacement for FGMM, (just 130 fps slower). About 1/3 MOA.
In the 20", I guess it's fully out of the node and shoots 2.5 MOA. That rifle shoots FGMM and even M118LR pretty well, but both of those loads run at 2600 from that barrel.
Very low ES in both rifles.
Possibly worth trying, depending on your needs.
