I tested & chronographed a few loads in my Rem 700BDL .375 RUM a few days ago. I started out with 93gns of H4350 and 270gn Barnes TSX which produced an 8 shot average of 2880fps. Next up was 97gns of RL19 with a 270gn Barnes TSX which produced a 5 shot average of 2743fps. I will probably try RL22 and W760 and see how they perform before making a final decision on which powder to stay with permanently.
