Hornady 22-250 superperformance

Isn't the Superformance just a rebadged "Light Magnum"? I know people say it is different, but they sure act the same in my 7mm08!
 
Kinda different, superformance uses a proprietary blend of powders that increase the speed without supposedly upping the pressure, while the light mag loads were a compressed load of a single kind of powder.
