Newest Nosler manual does not list that powder for that caliber and bullet weight. However, in the absence of a recommended powder charges, I would start at 60 grains and work up to a velocity of 2950 fps (the average velocity I have found using published data - i.e., Barnes #3, Hornady #8, Swift #1, Hodgdon online, Speer, Speer Deepcurl data, etc. With Barnes TTSXs, this velocity is achieved at 63.0 grains in my rifle.
