After talking to at least 2 respondents here maybe OSR is related to exceeding the modulus of elasticity of a given steel alloy. Mind you there were a few varieties around 1900, incl Krupps Flusstahl that was apparently very highly rated, then pom stuff, Poldi etc etc.
I definitely agree that the OSR issue appears to be indication of excursions outside the elastic limits of barrel steels.
Have you seen this thread?
I don't necessarily agree that hammering a bulged barrel back to shape is a great idea, but it's done anyway.
From what I've heard that happens to guns and rifles that have then gone on to pass proof.
I prefer to take a more prophylactic approach - by way of careful diet and care of what I have!
