I shoot a .284 Win with the same bullet and get excellent results with R17, the only powder I've tried thus far due to it's great performance. Whether it will perform as well in a taller, slimmer case is the question.

While it has been reported to be a little less temp resistant than some other R powders, among others, it performed perfectly for me at -20 F.
