I might add, it was always taught me by my BP mentors that the finer granulation you use, given equal charge weights, the higher your chamber pressure would be. iI was explained to me that this was because of the rate of burning. Apparently, the finer the granulation the more kernel surface area you have on a given charge. And, the more surface area you have the quicker it burns, thus raising chamber pressures. Again, this is just what was taught me by the old timers.
Somebody might prove that to be wrong but you won't get into trouble following that advice, I don't think.
Those are beautiful locks, Daryl.
