Doublespeak. The powder is a 'common commercial powder' yet has not match for handloaders.
For Hornady, I suspect that the difference is that a "common commercial powder" is available to any ammo maker as opposed to custom propellants developed specifically for them and are considered proprietary to Hornady. In one of the podcasts, they talked about working directly with St. Marks Powders to develop propellants for specific cartridge/bullet combinations. They mentioned that this started with the 375 Ruger and the Ruger Compact Magnums, so Hornady has been using these custom formulated propellants since 2006 or so. Only a couple, like Hodgdon's Leverevolution and Superformance ever became available to reloaders. My guess is that after those two, Hornady began to pay St. Marks to develop propellant formulations that would not be available to others.
