That would be correct but as you see on in the TPS tables service load pressures are lower than proof load. The Sherman Bell DGJ Damascus and Vulcan barrels ruptured at 29000psi


Correction. Check the TPS tables which I do not have in front of me. I believe the proof load for a 12 ga was 13000 in 1920 then rose to 15500 in the late 1920s. Just refer and follow the Parker tables in TPS.
