I have recently become interested again in developing loads for my .375 H&H as I just had irons installed and plan on replacing my guide gun with it for close range where my cabin is and bears frequent. I have 1 load I enjoy shooting 270gr TSX at 2500 fps. I have some 300gr nosler partitions I have 1 load done but need to test with RL-19. I was wondering if anybody has any suggestions for loads... I have RL-19 and W748 in bulk so either of those would be good. I have IMR 4350 in abundance too. I also have 1lb of 760 I could try. 270 and up grain dangerous game type bullets is what I plan to use. Thanks for the help guys.
