Interesting comments on 12L14, I know it’s a very popular steel for ML barrels, and has been used by some reputable barrel makers.
My barrel supplier would often supply me with 12L14 barrel stock for the smaller cals; 25-20 and 32-20.

WJL and or Brent, if either of you can supply me with the”hoop Strength” data or failure modem for 12L…It would be much appreciated.
