Actually, with one make of belted brass I have seen .020" of case expansion on the belt with FACTORY loads. This brass is obviously a lot softer than some others, but it held up fine.
This is also why the case-head method of pressure-guessing is kind of insane, especially given that most of us have a far better tool for the job these days, namely the chronograph.
Good Morning John. I agree. With out a chronograph I just don't know what I would do. They are the greatest thing sine sliced bread. Bear
