According to an article, a while back, in one of the gun magazines, the representatives of the various suppliers were asked which of their companies powders was best for the .308 Win./7.62 NATO. I don't remember IMR's response, but Winchester's was an emphatic W-748. He said it was THE powder designed for the .308. I haven't tried it, having pet loads using
W-760, but I just got an 8 lb. cannister of W-748, so I will be trying it soon.
I think IMR said 4895 was the powder they felt was best, but I am not sure.
