Remington 870 OH OWWW moment

    So I recently inherited a Remington 870. This gun has been in the family for over 15 years.

    I do not know anything about shotguns, the two guns I own are pistols. I went to the range and fired the shotgun with some friends over 100 rounds fired.

    I started reading about shotguns and found out that Chokes exist...I look at inside the gun's barrel and guess what, there is no choke inside it except for BARE threads....So I am wondering DID I JUST MESS UP THE BARREL ON THIS SHOTGUN? after firing so many rounds through that choke threads that didn't have any choke on it?

    They seem to be ok but I am not sure... Asked my grandpa where were the chokes he said he never used them...but I want to buy some, where would you get a couple decent priced Remington 870 Chokes?

    If you are going to use the gun for home defense then I wouldnt use chokes. At 7 to 10 yards a cylinder bore will still have a fairly tight pattern and you want to have some spread with a HD shotgun.

    Whats the ratio? a shotgun pattern will spread 1 inch every 10 feet on average with a smooth bore?

    As for the threads? Its designed to be shot both ways. choke in and choke out.

    No, it's not designed to be shot without a choke tube in.

    You probably didn't do any real damage to the barrel, but the threads may be ruined. Get a choke tube and see if it'll thread in. Look for the tubes on line, just google 'Rem choke tubes'.

    WRONG!!!!!! Do NOT shoot a barrel threaded for choke tubes without a choke tube in place! That is the FASTEST way to destroy the threads in that barrel!
    If I'm not mistaken, Remington even says this in their owner's manuals.
    For HD, you would get good service from either a CYL (Cylinder) choke or I/C or IC (Improved Cylinder) choke.

    Well said.
    Before you try to thread a proper fitting choke tube in place, use a bronze bore brush and some solvent to clean (gently) the threads, then dry.
    An old toothbrush would work well, too.
    I also suggest using some lube or 'Anti-seize' on the threads.
    Do NOT overtighten the choke tube(s), either.
    Those threads aren't deep. They can be damaged or destroyed!

    Oops my bad? I thought for sure you could take out the choke and shoot it? So do they have a cylinder bore choke to widen up the pattern?

    It's pretty nice
    It depends on what loads you and your grandpa put through it with the threads exposed. Steel shot will have ruined the threads most likely, lead will require some serious cleaning. The choke that came with the barrel probably got loose and went flying into the Belizean countryside some time ago. The barrel could be cut and re-threaded if they are destroyed but might not pay with plentiful new and used barrels for the 870.

    Thanks guys. I will clean the threads as soon as I reach home..

    I shot some birdshot and some buckshot the type that has 24 pellets in it I think. Both were lead.

    I am pretty sure my grandpa shot it a whole lot more times than I did without the choke on.

    I will get a Modified choke and see what happens. Thanks again

    Absolutely, you can get a 'cyl' choke tube.

    Take a look at Carlson Choke Tubes.

    They even list the constriction on the site. Carlson has a GREAT reputation!

    I got the .655 ventilator and a .675 hevi shot extended choke very cheap somewhere online, like $30 for both of them shipped. I'll try to figure out where if anyone is interested.

    If you go to the link you can actually read it. Yeah it's the way back machine, but it's a remington page from June 2009.

    Standard doctrine is that a cylinder bore shotgun barrel allows the pattern to spread about 1" per yard. It pays to pattern your shotgun so you can find out how it performs with different manufacturers' ammo and even different lot numbers. Then you have some idea of what the gun will do for you at different distances.

    I would find a gunsmith with the appropriate tap and have him "chase" the threads for you. If you try and insert a choke and cross thread it or have a burr and the threads become galled, you could ruin the barrel. Chances are with the wad being plastic and keeping the shot from contacting the barrel it's probably fine.
