krakyI have a fussy 300 ultra light. It does like the 150 tsx at about 3475fps but only shot the 168 mediocre.
It would be my advice to start with your favorite 180 max load and work up a grain..maybe 2 with the 168.
Here are some of barnes latest loads:
Bullet Weight: 168 gr Case Trim Length: 2.815" S.D. 0.253
Bullet Style: TSX BT Primer: Federal GM215M B.C. 0.404
COAL: 3.560" Barrel Length: 24"
Case: R-P Twist Rate: 1:10"
Charge Velocity Charge Velocity Load
