I reloaded .308 WIN ammo for years with good results using 150 and 155 gr. bullets, but best results loading 168 gr Sierra Hollow Point Boat Tailed bullets with a powder charge producing 2600-2800 FPS. I advise consulting at least two different newly published reloading manuals. Follow powder charge weight recommendations to the letter (or grain weight number, as the case may be). Good shooting.
