Re: 6BRX light bullet reloading data
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
