I need to get some more BM1 and work it up a little more. I think there is another half to full grain in it before pressure is an issue. Should get those Scenars out at nearly 3000fps - 2950 may be good.
I did do some workups with the 100gn NBTs over BM1 and manged to get them going at just over 3000fps (3043 IIRC) but I felt the brass was getting smashed a little hard. SD and ES numbers were single digit though.
One thing I have learnt is that what works in an AR15 Grendel is not always the best thing in a bolt Grendel. Still exploring this so I'm not confirmed on it yet.
