IMPORTANT ADDENDUM: It looks like the British (Gamebore, Eley, Kent) and B&P and Fiocchi pressures are CIP and not SAAMI, so by US measurement, are actually 400-800 psi more than reported. The B&P F2 Classic is reported to run 9867 but actual testing by Armbrust showed it to be 10,500. The Gamebore Traditional Game 1 oz is reported at 8122 but testing showed it to be 8400. The Fiocchi website states "All products are loaded to either C.I.P. or SAAMI specifications." The Fiocchi 16GT 1 oz. load is reported to run 6810 psi, but actual pressure testing by Tom Armbrust showed it to be 7500 psi SO they must be using CIP data.
