That is not moly on the Winchester loads, it is Lubalox.
Very easy to duplicate that load.
Fire the factory rounds over the chrono and record velocity.
Pick up some CT ballistic tips, load them to the same OAL, pick up some IMR4064 and try to duplicate the velocity of the factory loads.
Homemade Winchester supreme ammo.
