6mmBRX case is 43 gr H20 at overflow
6mmBR case is 37.8 gr H20 at overflow [14% less capacity]

I have been shooting 6mmBR:

65 gr Vmax moly W748 33.5 gr [all that will fit] 2.22" OAL, but the chamber will seat it further.
Quickload thinks that this is 3229 fps 45,801 psi

87gr Vmax moly 33 gr H335 2.290" OAL [jammed into the lands, the bullet will seat that much further anyway]
Quickload predicts 69,191 psi, 3,161 fps

H-322 or VV-133 is perfect for my 6 Dashers with 55gr Ballistic Tips in bolt guns with moly.

The loads are for you to find......
