As far as “minimum wall thickness” that I’m comfortable with, it depends on the gun and what cartridges I plan on shooting through it, but I am ok with spots down as low as .018 at the 9” from breech mark. Obviously over .020” is preferred. This assumes suitably thick and unaltered chambers and barrels in otherwise good condition.
