Does anyone know of any sane reloaders trying these powders in the .378? From what I've seen, RL19, RL22 and IMR7828 appear to be the velocity kings in the .378, but I was wondering whether the newer powders could achieve any velocity gains since their nominal burn rates appeared suitable for use.

I don't know the answer to your question but just have to ask: You need more velocity in a .378?

This is AR, where too much is not enough.

Ah, yes, well, good point. I just shudder at the thought of the recoil of a 300 grain bullet going even faster than it already does in that cartridge.....

in the 416 Bee yes....not in the 378
