Factory duplicate Gold Dot loads?

I think what they are referring to as "efficiency" is if with one powder you can get 950fps using 10grs of powder for example and using 20 grs of another only gains you 50fps the first example would be deemed much more efficient and the later not so much.

Understood. But since the ACP case is small and that powder can hit 1000fps with a 230gr bullet out of a 5" barrel without going +p, efficiency is in the eye of the beer-holder.
