Even (or maybe especially) armed with all this guesswork, I would not build a rifle with steel having yield strength of only 26,000psi -
THAT IS SCARY!
The steel's yield strength is 53'000 psi, if I use that as the tensile strength value in the formula it gives me the point at which the barrel will begin to yield to the pressure, in this case around 26'000 psi. Actual burst pressure estimated at 31'000 psi.
