Just for information, ammo manufacturers do not load with the same powders that are available to reloaders. Reloading powder has to stay consistent from lot to lot so that the information developed for each load is consistent over many years, even decades. When manufacturers load they go for velocity and pressure consistency for each load developed. They blend many different kinds of powder to achieve their goal. They also buy powder by the ton. They use the cheapest bulk powder that they can find and use as little as possible to reach their goal. I am not involved in the loading of ammo but I do work for W-W. Hodgdon makes all of W-W powder and just sells it in W-W branded containers.
