I’ve seen old revolvers with very thin cylinder wall thickness, like these for example https://www.kirstkonverter.com/ruger-old-army/ruger-converters.gif
Back in the days the quality of the steel was inferior, so it got me to wounder about the steels of today.
What’s the minimum thickness of a chamber in cal .40 containing a 25-30 grain FFFG black powder (or equivalent pyrodex P) load with a 92 grain lead roundball tightly infront of it (+wadding) if it’s made of a steel with following properties:
Yield strength min [MPa]
700
Tensile strength [MPa]
900-1050
Elongation A5 [%]
12
Hardness
270-325 HB
And how many PSI will such a load described above generate?
