I'm helping a friend of mine that lives in SA work up some loads for his .338 Win and .270, but I need to know what gunpowders are available so I can suggest some loads. For the .338 we're looking for 2800 FPS with 225 Barnes TTSX. If you don't have the exact loads then I can suggest some if I know what powders can be had locally. You know, something in the H4350 range (on the slow side). Can you help?
