OL' JOE IS CORRECT, THE MAJOR AMMO MANFACTURERS ORDER X AMOUNT OF X POWDER AND THEN LOAD TO A PRESSURE LEVEL. FROM WHAT I UNDERSTAND THEY DO NOT UTILIZE A PER GRAIN MEASURE.

SO WE CAN'T DUPLICATE THEIR POWDER, AND I DOUBT WE COULD EVER DUPLICATE THEIR LOADS. WE COULD PICK A CERTAIN POWDER AND BULLET WEIGHT AND DUPLICATE THE FACTORY VELOCITIES BUT THATS AS CLOSE AS WE MERE MORTALS CAN GET.

NOW, THIS INFO IS JUST WHAT I HAVE READ, SOMEONE ELSE MAY COME UP WITH ADDITIONAL INFO.
