I have piezoelectric transducers that I use in pressure test barrels on universal receivers, so I know exactly what pressures I am running. I also have access to powders that are not made available to the general public. One of the perks for working in the firearms industry.
Velocity is always measured from the barrel that will be used for hunting, not just pressure barrels, as the bore diameter, length and choke has an affect on velocity readings.
