Check this link for recommended load.
Manufacturers offer tons of stuff on line.
You need to start investing in some good reloading books as well.
A great cartridge. While not at the top of many lists for that combination I get great accuracy at acceptible velocities with IMR 4831 and 100 grain Nosler Partitians. Haven't felt the need to change.

I won't give you any load data but I will tell you the bullet you selected is a very good one for this caliber. It will work well on deer sized game.
