130gr Nosler Partition 60.0 H4831SC
3100 almost exactly out of my 22" Custom Ottmar/Grisel as measured by lab radar.
I never shot the Barnes out of that rifle but let me look, I may have shot the 130 TSX out of a Biesen I once owned.
59.5 H4831SC and the 130 TTSX chronoed 3075 out of the Biesen. Interestingly, 60g jumped the velocity up over 3,200 fps.
64.0gr of Magpro and the TTSX gave just over 3,100 with excellent extreme spreads.
