Steve,
Thanks for taking the time to answer. I did as you suggested and it felt a little tight. Maybe my imagination. Measured the paper at .003 and tried newspaper at .002. When it closes it feels and looks tight but the barrels are a couple of thousandths high at the upper outboard position (if that makes sense)of the breech balls. There is still about .006 or so between the bottom of the barrels and the water table. I can see some light at the intersection of the standing breach and water table.
