A few of the powders suitable for light weight 308 bullets (110-130) will work in the 223, 308, and 7.62x39. And, oddly enough, a bullet of about the same weight in either the 308 or 7.62x39 can use the same powder (not the same amount) in most cases.
Reloader#7, 4198, H-322 are some of the ones listed in my Hornady book. I use the same powders in 55 grain 223, 300 Blk, and 38-55.
As you move to heavy (150grain) 7.62x39, W748 and a few others are useable.
