Larry, have you run the numbers, 7016.9 grains vs. 7019.8 grains? No kidding, that's not a particularly deep hole.

Anyway, you started off acknowledging 'felt' and 'perceived', why did you drop it? At the very least, can't we show the graphs 'proving' the necessarily higher pressure a faster powder needs to develop due to shorter duration, to get the same total force under the curve?
