I've been fortunate to have used many combinations of weight and construction bullets in the .375 H&H on a lot of different things in a lot of different places. More and more I find the exact bullet doesn't even matter, hell I've now taken a Wood Bison bull, Wildebeest, Bear, Lynx, and Lion with Federal blue box RN SPs of all things. I blame that on fatherhood and a lack of time, scantly stocked northern shelves, and I seem to be without the foresight to mail order. I still load 300gr the rare times I get to the reloading bench now, principally TSXs just because I have a lot of good results with them and data to match. At every practical hunting range I'm finding it less and less critical the exact bullet I choose. I do like non-toxic, and thus favour the monos, and have good history with the TSX so I generally stick with it. Suppose in summary I don't find the .375 H&H too fussy, it always works for me whatever it's stoked with. One notable exception for me is the lead core 235grs, notably the Speer Hotcor- this one has failed for me miserably.
