There is some published data in the manuals and you can also use 280 AI data too as they are close in capacity. Same powders work in both.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
