6mm ppc and N133 H322

In the late 90's 322 was changed and the color went from a black to a greenish shade. This changed how the powder reacted and burned in a 6 ppc case and it frustrated enough people that they went looking somewhere else and they found n133 was able to tune better than the new 322. Rumor was that they removed the graphite from the 322 and that was why the color change.
