You can probably duplicate the Federal load to some extent. Like said, you now have a lot if the j formation you need.
Federal case
Federal LRP
150gr Nosler Partition
Use the OAL of the factory ammo
Since Federal is part of ATK they might be using Alliant powders but not necessarily. Speer is more likely to be using all in-house components. I would take one if the factory loads apart and at least check the powder weight and see if it's extruded or spherical powder. I know it's almost impossible to ID powder from looks but it can't hurt to look. You can even put the factory round back together not to waste a round.
