If I exhaust my supply of 168 TTSX, I may switch to Barnes 175 LRX for a wee bit better BC.

I have been using Magnum in the 300 RUM with the 168 TTSX's as well. I am glad I tried it, accurate and excellent speed with that rifle and Magnum seems very available.
Mule Deer also reported that RS Magnum is pretty temperature stable although it is not advertised as such. I have most of a pound of Magnum but saw some stock at LGS, so I might pick up an extra pound just in case…

It works excellent in my 6.5 PRC as well. It's one of the powders I never paid attention too until others started getting harder to get.
