140 Trophy bonded tip
R17, R19, R26, Hunter and Magpro
7mm-08
140 Trophy Bonded tip

Thanks Doc, is the TBBC trophy bonded bear claw right? Does quickloads have the new tipped version? Cause that's what I have, the tipped version that has groves in the shank. Also in the 7-08 what about Big game and varget powders? maybe I could use the TBBC data for the tipped grooved version. thanks
