WB like to experiment with powders that are not normal to

certain loads. I don't have the time. I go with the powders that are the same as Unique, 1680, AA#9, AA#7, 296, H-110, and so on. Each lot varies especially military grade powder so I normally drop it 10% from what the equivalent commercial powder would be and work up. I have got some WC820 that is supposed to be the equivalent of H-110 but it was considerably hotter so I dropped it back 10% and it equaled H-110. Some lots are the same as AA#9. But they tell you in the data to drop your load a bit and work up. All in all it is a good way to save if you shoot a lot and we shoot around 1000 rounds a week here and 90% of that I load so the bulk powder saves us considerably.
