    no difference. The terms refer to a barrel with an ID larger than the standard diameter.

    Hmm...I thought the difference was that an overbored barrel started that way from the factory, and so, didn't affect the thickness of the barrel wall. Where a backboring is done afterwards and results in thinner barrel walls. The result is more or less the same, a larger than standard bore, but the process is different.

    Might be just splitting hairs and I might be wrong, which wouldn't be unusual.

    You're correct about the difference, you're not wrong, and you're not splitting hairs.

    Then why does Browning use the term "backbored" in their INV+ guns?

    You say potato, I say potato.

    zzt has it right.

    Because the guy writing the copy for Browning doesn't know better, and wouldn't care if he did. Probably doesn't even own a shotgun.

    From the link shown above:

    "4) Backboring: The nominal interior diameter of a 12 gauge
    shotgun barrel is .729", but your barrel could measure anything from
    .720" to .800" and still handle a 12 gauge shell. Anything bigger than
    .729" is technically overbore or backbored. Stan Baker, Seattle
    gunsmith, claims to have coined the term "backbore" in order to avoid
    the less attractive connotation of "overbore". They mean the same thing."

    Looking for some support on the internet to substantiate my definitions of "overbore" and "backbore" as I had heard them in the past, I found the following:

    Based on the above, I hereby respectfully withdraw my argument and leave timb99 and jhoward hanging out to dry by themselves like the traitor that I am.
