Many find the SR 4756 to be one of the best powders for the .40 S&W and some like it best for the 9x19 (Luger), too. Reasons? Lower pressure but still fine velocity and accuracy. My daughter has found the SR 4759 to be her powder of choice for a reduced load in her .257 Roberts with 100g Spitzer (better groups than with the 117 factory loads).
