    Hey there John Taylor.
    How much can you safely take out of Pietta .44's chambers?
    Enough to make the chambers a couple thou over groove?

    Usually the chambers are only a few thousandth under the groove diameter so most of the time it only needs about .004" reamed out. That's .002" per side so the wall thickness is about half the thickness of a sheet of paper thinner.
