Let's assume the barrel is deeply pitted (or has been honed) and the wall thickness is dangerously thin. You tie the barrel in an old tire and remotely take 10 shots with low pressure RSTs; but the pressure generated is above the yield strength of the barrel wall. Each shot produces "low cycle fatigue" plastic deformation of the steel, which may not be measurable when checking for barrel bulging with a micrometer. With shot #11 the barrel bursts, sending a chunk of shrapnel toward the head of your hunting companion...or grandchild. And you own that shrapnel. Why take the risk?
