IMR 4064 all the way. It doesn't meter well but it shoots great!

Hodgdons Reloading Data Center lists 21 different powders and 11 bullet weights that are satisfactory for the .308.

Actually, if you want to get technical about it, your powder choice is dependent upon your bullet choice--your bullet weight, and thus your powder burn rate. To recommend a powder we would need to know what bullet you intend to use.

Check Hodgdons Reloading Data Center.

for my .308 ive been using IMR3031.

In the mid 60s i ran accuracy tests with all .308 suitable powders produced at the time: IMR 3031 gave the best accuracy and i've used it almost exclusively since. My tests showed IMR 3031 was the best powder for .223 and i've used it exclusively in that caliber since. No need to change something that works.
