dammitman,
The rule of thumb I learned and seems to work OK for me is to use 10% reduced charge for military brass. So, if the data book calls 25 grains of powder a maximum, (for a conventional case) use 22.5 as a maximum charge for military cases.

I find that maximum loads for conventional cases can fill a military case too full.
