conclusion: Universal works really well at both ends of the bullet spectrum and it's easy to make major power factor with the 180 grain bullets, even with the Steyr 4" barrel. Low flash, low perceived recoil, accurate, and burns clean at moderate to heavy loads. And I can find this powder easily locally. It's a keeper for me at the moment.
