Late last night I purchased a Winchester M70 Safari Express chambered in .375 H&H. I am heading to the Eastern Cape in South Africa in June. I am going to be taking this rifle as well as my .300 Win Mag (there is another thread about that one). My PH suggests 260 grain bullets for the .375, as we are going to be hunting PG only. Eland, Kudu, and Zebra are on the agenda. I am working up a load using 260 grain Nosler Partitions. My starting load was 76.5 grains of IMR 4831 with a Fed 215 primer and a C.O.L. of 3.495". I fired 2 5-shot groups today. It was about 40 degrees Fahrenheit and clear. All shooting was at 100 yards. Group #1 average of 2390 fps group size 2.761" or 2.64 MOA Group #2 average of 2397 fps group size of 1.534" or 1.48 MOA Average group was thus 2.15" or 2.06 MOA. This is a lower velocity than I am aiming for, and I'd like to get the rifle dialed in to sub-MOA if possible. Does anyone have any experience loading 260 grain bullets for the .375 H&H? Are their other powders I should be trying? Any experience with optimal charge weights? Thanks.
