The barrel's threads measure about 1.04" across the tops of the threads, though that measurement is tough to precisely for some reason. Behind the threads, over the funneled part of the barrel, it measures 0.999". In front of the shoulder it measures 1.145".

There is a little damage to the funneled part of the barrel. It looks like it took some impact with the concrete, and maybe some other metal pieces which made nicks and dents, but clearly, the barrel does not appear to be expanded in any significant way.

I don't know what "normal" should be for these measurements, but that's what I have on this one.

I sure would like to know the pressures that Michael's load developed. Does anyone have a book with pressure numbers for that load?
