What are your best loads for 338 rum using 300 gr Bergers? I have had some success with 90.5 gr Retumbo. What would be another good powder to try out and what gr?

H1000 or R33

RL25 did excellent in my 338 rum with 300 gr SMK, my load was 90.0 gr. I had a super low es and excellent accuracy. RL33 isn't available yet and I think it will be tough to get for awhile.RL25 has also given the best results in my 338 edge. Start lower and work up.
