Anything special about it? Are there powders that are too slow or fast? Bullets will be Speer 150 gr Hot Cores.
I reckon any powder suitable for the 308 is good to go since the gas can be regulated.
Just keep in mind that the action isn't the stiffest in the World, so don't load it hot if you like your brass. Anything you'd put in an M14 is OK, but like Dave said, you can adjust the gas to make up for a lot of sins of burn rate.
