H380 is a superb powder for my 308
I also have had very good results with 4064(IMR-dupont)
and also Accurate2230
sorry, I don't have the charge weights before me to share. Besides they may not work for you. My 788 has a 16-1/2" barrel and my loads my be differnt than what you need.
I will add: I never liked anything lighter than 125gr and nothing heavier than 165gr
I always wished they made a 140gr bullet for 30cal. I thought that would been the best bullet. Who knows, I never could find any that weight.
again, just my results
