RPr,

Confusion comes with the territory on this one. Coxe never states how much FFFG he used. At 9,000 psi, they were duplicating many of the old black powder proof house loads. These were for max pressures rather than service pressures.

What is interesting is how quickly some of the other powders shed their pressure when compared to black powder.

The loads I quoted above from the Lyman book are actual working service loads.
