And what tool was used to measure the diameter. I have a Skeets gauge, it works well but wont give the readings consistent like a internal micrometer will. Lot of mechanism and distance between the feelers and dial. 3 thousandth slop is about what I expect.
Of course my internal mike that reads half a thou consistently will only measure a inch deep. My take away is something like a Skeets gauge gives a good indication of bore size and choke constrictions, dont be too concerned about accuracy. Precision deep internal micrometer cost way more than most of us want to spend.
Apologys In advance if the measurement is precise.
