    Anyone know the bore diameter of a 870 wingmaster pump? I bought one yesterday, 30" full and I want to have chokes installed. I appreciate your help,

    .727 to .729 is the usual range, but it can be higher or lower.

    That will probably cost more than the bbl. did. Better of to buy one with rem-chokes.

    You are best off having it measured, the old fixed choke barrels can vary a LOT

    I have one of the bore dial indicators and have measured Rem 870 barrels anywhere from .724 all the way up to .740 and none of these were marked as any sort of special barrel.

    Anybody installing chokes will measure the bore so that shouldn't be an issue.

    Most of those 870 full choke barrels patterned pretty darn good. if you are wanting to do different things, then buy a factory remchoke barrel. It'll be a lot cheaper and have great resale value.

    What Shrek said. I have a new 870 with a .724" bore, and an old Magnum Steel Shot barrel with a .738" bore. Had an 870 Competition with a .742" bore. My 8 year old 870P has a .735" bore.
