In case anyone is interested Ive heard back from alliant:
Here are some suggestions:
115 lead Bullseye 4 grs, Unique 4.5 grs, Power Pistol 5 grs
124 gr lead Bullseye 3.8 grs, Unique 4.3 grs, Power Pistol 5 grs
135 gr no data
147 gr lead Bullseye 3.3 grs, Unique 3.5 grs, Power Pistol 4.3 grs
In all instances, reload just a few to begin with to be sure they will
cycle the action of your pistol before reloading a quantity. Thanks for
your note.
