I have used my 375 RUM in Africa several times . 300 grain TSX with 100 gr 7828 is just above 2860 fps and is very accurate.95 grains of h 4831 with 300 north forks is a hammer. I have had poor luck with 300 nosler partitions on big game buff etc. I am sure they will be great on plains game . It is a great round and I don't find recoil that bad and I have no break. My gun is AHR custom made on CZ action.
