My favorite 308 powder is Varget, followed closely by Reloder 15. I've done well with 4064, 3031, TAC, and 4895. You can get good results with a lot of powders in a 308.
You don't say what for, but almost any good bullet will work. I've been impressed with 130 gr TTSX's @ 3050 fps. But I've also gotten very good results with 155 Gr Bergers, as well as almost any 150-165 gr bullet from all of the major bullet makers.
