Since you use more grains of PP than Unique its not as economical.

IMO, Power Pistol out performs Unique in
full power 45ACP loads, like "+P" & 45 Super. It's slower & denser, which is what's needed for these. Try the documented 11.3grs. under a 185 JHP, in a Super case and a properly setup 1911, or 325/625, to see. I like & use Unique too, but there's no comparision in this setting.
