If you're asking about loading that bullet in a .308 Winchester there are many good powders. 4895, IMR4064, IMR4007, Varget and BL-C(2) are all good powders in the .308 Winchester. There is also a new powder from Hodgdon, CFE 223 which is supposed to be good but I have bot tried it yet.Was just wondering what powder is suited for best .308 175gr.matchkings,will be using remington brass and cci br primers.Thanks
