    The amount of "choke" is the difference between the bore diameter and the choke diameter at its smallest point. Unless you know the bore diameter in advance, knowing the diameter of the choke doesn't tell you anything.

    For example, modern Browning shotguns have about .740" diameter bores. A choke of .720" in the end of such a barrel would give about a Modified pattern.

    A Beretta Mobil choke gun such as the 390 and some of the earlier 391's has a bore diameter of about .722". A choke of .720" diameter would be about a loose Skeet choke, while this same choke diameter in a modern Browning would be a Modified choke.
