Wooters old load
John Wooters was a reloader and hunter of note and he wrote that his favorite .308 hunting load was a 150 SP and 46 gr of 4064. That charge weight is not a maximum in two manuals I just checked, BUT........
Components and rifles vary and I would start lower as suggested and work up to it.
I've moved away from 46 gr to 45 for hunting loads, and my FMJ practice loads with 147 gr slugs get 44.5, just to ease wear and tear on my rifles.
