A barrel is a thick walled pressure vessel with open ends. R=Ri Po=0
Unless you only shoot bull barrels I can guarantee you, that you've shot plenty of barrels well below an FoS of 3.
Is just a reference, notice thin wall vessels were 3.5-6!
So, let's see some reverse calculations. Maybe the numbers would tell us what kind of FoS a high pressure cartridge is likely designed to, working backwards from known dimensions, materials and pressures?
