Amature powder "blending" is as old as reloading and it has never worked well. In the "old" days shooters had few powders to choose from but today we have such a profusion of burn rates it's not needed.

The perception between what ammo makers use and what we can buy is vastly over rated; the difference isn't much and it's often none at all. The ONLY difference between what the ammo makers use and our's is that we get 'cannister powders', being those lots that fall into a very narrow burn rate that permits us to work with it without all the technicians and test equipment the big boys have.

As mentioned previously, the modest blending by ammo makers is only a slight mixing of different lots of the same general type done by careful testing, it's NOT a whimsical mix of wholly different powders done by guess and by golly.
