Back when I loaded .308, I used W-748 for 150-165gr. bullets and IMR 4895 and IMR 3031 for 180gr. I now load only for .257 Roberts and .35 Whelen using IMR 4064 and would use it for .308 if I loaded it now. It is a very versatile powder which yields excellent accuracy, I chose it after extensive research and range testing.
