.308 Barnes 168 TSX starting load

[woodteacher]

I need a starting load for 168 gr. Barnes TSX in .308 rifle. Don't have a Barnes manual. I have every one but it. Powders I have on hand are IMR 4895, H4831sc, H4350, Ball C-2, H380, IMR4831, IMR3031, and some AA powders. I understand at the Barnes site they say use x-bullet data but the loads they show are using powders that I currently do not have. Any help would be appreciated. I currently use IMR 4895, 47 grs. and a Nosler 150 gr. partition. Shoots great and works great on Missouri whitetails but just wanted to try the Barnes. Also have some MRX 165's. Also OAL information for these bullets would help.
