    Eddie, Sure don't know what the specs may have been for manufacturing, but that is sure some tight. I do remember checking either an old Fox or Mdl 12 that was high up in the 40 or 50'ish. I would think that to be outside of the norm. The proof is in the pudding, do some patterning although you've already said you're happy with it. Maybe -- better off not to know. LOL Shoot often while we can, Bob

    I recently purchased a 32" Model 12 made in 1927 and while I can't measure the bore diameter, the choke at the muzzle measures 0.694", the same as my other gun made in 1949.

    Thats why Model 12's are still king of the game guns I have a 3 inch duck gun with 40th choke just for games and I love the old gun anyhow need to fine a reason to shoot it more.

    I wonder if some one had it chocked down for the X shooting in turkey matches. I know some did it to winchester 37.

    Mine measures .684. I assume a bore of .729 for .045 of choke.

    I assume that the felt wads did not get the job done as well as today's.

    You didn't say if it was a standard Mod 12 or a 3 incher!

    32 inch barrel and that tight a choke seems to indicate a "duck" gun ... if so, then it would be normal.

    Yes! They do smoke target ... all the way from the parking lot!

    My Model 12 Y is choked .047. Nice and tight.
    It will vaporize targets.

    What kind of rib is on that Model 12 Ed? Do you have a few more pics, it looks pretty interesting.

    Thank you, Rodbuster.

    The bore on most was .725 and very tight full chokes .675-.690 was not un-usual.

    Not as bad as you think Eddie. Laughing my fanny off, with you, not at you. I hope I truly wasn't the motivator for making you do that. I think Neil could tell you how many hundreds of shots, charts, and variations you can find testing with that gun. Now you're going to make me find the couple of tight ones I have to play with. One was a K-80 barrel at 48 if I remember correctly. It handled light loads well. Have fun and shoot often, Bob

    I think you're correct. It should like those loads. It's obvious that you are using a bore mic. That and a trigger scale are probably the two best tools and fun to use for a shotgunner. Enjoy while we can, Bob

    Wow! Most of the full choke Winchester barrels I have come across have been in the 0.035" range, maybe +/- 0.004". Winchester seemed to get more choke with less constriction than other makers. That said, I've never been of the impression that there was one unique profile or constriction that identified a barrel as Winchester. But hey, they're just numbers. It's the pattern board that counts.

    I own several Model 12's and all of them have more than .040 restriction, the ones I have sold all had over .040 restriction and all of them have been pre 1964 vintage also ... I have checked the chokes on all of them and they go from .735 to .730 so yes they are tight, that being said the bores measure in the .690 area on them ... WPT ... (YAC) ...

    Checked a few of my Model 12's. I have always been interested in chokes too.

    1916 30" field bore .726 Choke .031
    1917 32" '' '' .728 '' .033
    1920 32" '' '' .728 '' .031
    1922 28" '' '' .724 '' .031
    1936 32" Mag '' .726 '' .034
    1948 30" Trap '' .731 '' .039
    1949 30" Trap '' .726 '' .034
    1955 30" Mag '' .727 '' .032
    1958 30" field '' .727 '' .038

    What this proves to me is that there is lots of variation in both bores and chokes. Enjoy, Joe Griffith

    I have been measuring chokes on Model 12s for many years and many guns. I have never measured a factory full that is tighter than .039.

    I just measured the three that I presently own using a dial gauge bore reader with the following results --- a 1961 trap measured 0.727/0.695 for 0.032 constriction --- an early "Y" trap serial 2018XXX measured 0.732/0.691 for 0.041 constriction --- a 1963 trap has a bore of 0.731 but has been threaded for Briley thin-wall tubes.
