Wow! Great information. I have been curious about AA2200.
I should have check this out first before I commented, but I have no prior knowledge of the 25 x 6.8 by Black Hole. IF that cartridge is simply a necked down version of the 6.8, then the case capacity will be the same as an unfireformed 25 DTI -- which is 35 grains of H20. The vast majority of these loads are WAY overpressure.
