Having a rifle built and now I need to think about loads. Never loaded for the .338, but I have some IMR4831, IMR4350, and RE 17/19/22.

I am wanting to work around a 225 grain bullet. I am thinking possibly a TSX, Partition, or A Frame. I want a tougher bullet as I built this rifle for a plains game hunt and it will be used for animals up to Eland.

Any loads, feedback, advice appreciated. Because we will be in Africa, I plan to back loads off at least 100 FPS to ensure heat/humidity doesn't put me in any overpressure situations. I think I would be just fine with a good 225 grain load in the 27-2800 FPS range (24" barrel)
