Let's do the math on that one, 12.5 times 11,0000 psi (the standard proof load) is 137,500 psi before barrel failure (for both Damascus and early fluid-steel tubes). Talk about a safety margin! Admittedly, there are plenty of unaccounted-for variables here, but.....wow, what was I worrying about again?
