Drew, you should know better than to trust those sneaky Italians!:)
Birmingham Proof House says: "CIP crusher service pressure for High Performance (magnum) is 900 bar service, proof 1200 bar; the transducer values are 1050 bar service, 1370 bar proof."
Sometimes what you read on the shell boxes isn't correct. For example, on a box of Gamebore Pure Gold 65MM shells, it says that the shells can be used in guns "proofed to a service pressure of 3 tons per square inch (850 kg per square cm)." But we know that while 3 tons is a service pressure, 850 kg (bars) is in fact a proof pressure.
