hmmm....not guessing

"Accuracy, and low flash?"

In no particular order, except the best choice first:

-3N37 (yes, Vihtavuori powders cost more)
-Silhouette (also can be WAP )

Suggest using 'Start' data with these choices and your bullet, and use .2g increments when working carefully upward.
Do NOT let you OAL get shorter than 1.115"; suggest start OAL of 1.125" minimum.
Sort 40 S&W cases for best accuracy; recommend Federal primers for accuracy development.
