Thak you William for saying so well what I was trying in my feeble way to say. Everyone understand when I mentioned the higher bbl pressures of the slow powder loads This was not meant to imply they would "Spike" to dangerous pressures, but simply that what was lost at the beginning would be caught up further on, the pressure will not remain lower all the way down the bbl, the curves will in fact cross. The attempt is actually to more or less replicate Black powder performance which when loaded to the same terminal ballistics will also have a higher "Barrel" pressure than will a fast smokeless. The big fly in the ointment here is that while black will burn at essentially the same rate under any imaginable pressures, these slow smokleless powders loaded to very low pressures can become exceedingly unreliable.
