    Kind of a gunsmithing question, but I've got a mossy 500 12 guage, It was the two barrel set, 18 1/2" cylinder bore and 26 or 28" mod barrel. I like the handiness of the 18 1/2" but cylinder bore is kind of worthless IMO. Could a guy thread the barrel to fit remington style chokes? I have an 870 with a full line of chokes. My father-in-law is a machinist, and my old man is pretty handy with a lathe, so if anyone has any info or suggestions, that'd be awesome. thanks in advance.

    I don't think i understand why you would want to choke the shorter barrel? Are you planning on hunting with a barrel marketed/designed more for close range and/or home defense use?

    I have a similar setup & have found the pattern of shot from even target loads to be not much larger than a plate at 20 yards, maybe mine is weird or i had weird ammo.

    yeah, I'm looking to hunt with it, rabbit, squirrel, bird, etc. Just trying to make a little more versitile. With my setup, the short barrel's effective range is 10-15 yards. at twenty it's reaching a 2ft+ pattern. Granted I'm just shooting cheap target loads. I know the barrel is designed for self defence, but it's not my personal choice for that.

    If the barrel is indicated to zero on a programmable or cycle lathe, there should be no issue with cutting threads as long as you know the specs.

    Some people may even use a die series....


    I'm not sure, but I would think that some states have modifacation laws. Some places are kinda funny that way...

    So do you think it'd actually work? or does a Cylinder bore vs a choked barrel have different Inside diameters, or tapers? I really don't know a lot about shotguns.

    Mossberg 500 series is a very popular model of shotgun. My first thought is yes, you can. However, you would probably want to call a local gunsmith shop or even a local gun store. They should be able to tell you yes or no based on the information youv posted here.

    If also don't know enough about machining either, then I agree with BigByrd and consult a gunsmith. I did specify knowing the specs first.

    I guess I'll just have to mic everything out when i get back into town. as long as i have enough material on the barrel after machining it to fit flush to barrel, i'll be fine.

    Not to take anything away from you, your father or father-in-law, but when altering a firearm it's best to leave it to the ones that know/have studied; ammo ballistics, functioning of firearms, dynamics of shotgun barrels, the firing & effects, etc.

    Here in Florida shotguns are very popular. There's a place that can help you with your project. Go to: Rhino Gun Cases, Inc, Turkey chokes and shotgun chokes on the top tool bar click on Gunsmith and Barrel Work

    This is a quote from the website...
    Cut, tap and thread barrel $115/barrel

    Rhino chokes are made here in Florida and very popular around here.
    High quality, proven performance, that's the only choke I'll use for all my shotgun's needs.

    Do you have a set of id mics or quality bore gauge? Also, keep in mind that fine threads are best cut with an insert made for the fine threads and high tpi.

    Try a good game load first.

    I'd try a good game load in it first. I've been hunting rabbits with my Mossy 500 20ga for years using the slug barrel (cylinder bore). I load 1oz #6 to 1300fps and the combo works great. Perhaps the cheap loads you are using are the problem and not the barrel.

    Tools and measurements required for Rem-Choke installation.
    12 gauge
    Minimum barrel OD----.850".
    Maximum barrel ID----.740"
    Minimum barrel thickness after machining----.018"

    The work can be done by hand, but is highly recemended to be done on a lathe and by a gunsmith familiar with choke tube installation.
