    I bought a DT10 from a TS.com member yesterday! I am measuring the chokes that came with the gun but without the knowing the bore diameter(No, I do not have a bore mike) I do not know what I have! I could not find it in the manual!! Can any of you tell me what it is supposed to be so that I have a starting point! I will get it measured but I can't right now! Thanks, Tom Rhoads

    You won't have a starting point until you have the bore measured. HMB

    Mine measure 0.735 with a bore gauge

    They are labeled "18.6"

    18.6 millimeters = 0.732283465 inches

    Some italian mfgs (perazzi being one) stamp the ID of the barrels in MM somewhere near the chamber under the foreend. Never checked a beretta to see if its the same case, but it couldn't hurt to look (should say somewhere b/w 18.3 and 18.8, depending on the actual ID, and from there you can convert to thousandths of an inch).

    The barrels MEASURED bore will be stamped close to the barrel flats. It is part of the proof process.

    UNLESS some owner during the life of this gun has had the barrels backbored or worked by one of the barrel gurus. Unless it is brand spanking new "Never take for granted always measure". I learned this lesson the hard way.
