In case you are not already aware...
The manufacturer of Shooters World Powder used to be the supplier for many powders in the Accurate line-up, maybe a decade ago. So a version of the current powder called Auto Pistol powder used to be supplied to Accurate as AA-5. I was shooting it back then, you may not have. The factory is located in the Czech Republic. Current AA-5 is from a domestic source. Totally different powders but with similar density and burn rates.
Shooters World Powders are excellent and the current handgun formula have flash suppression and temp sensitivity enhancements. Overall, performance with these powders is excellent and they measure like liquid graphite.
As to that...the only issue one may encounter is that the handgun powders are so finely grained that they can leak somewhat from slide-bar type powder measures like the Dillon and Lee. It gets on the shell plate and has to be cleaned off. The measures have to be tightened up to eliminate this.
The rifle powders are also very good... they offer both single and double base powders and you have to read the description carefully to figure out which is which.
