    Modifing Shotgun Barrel For Steel Shot

    I have a Beretta Mod. A-M-301-12ga. Magnum, 3", 30" barrel, full choke, Semi Auto shotgun.
    Purchased in 1977 and is pre-steel shot requirement.

    What are my options to modify for steel shot use ?

    There are a lot of knowledgeable people on this site and would appreciate/ hope for some help.

    Cheapest option is to find do a gunsmith who will ream the choke to a modified, or around .020 to .025 constriction. Best way is to have barrel sent to Briley in the US and have them install their tubes, but this will be expensive. There MAY be someone in Canada who will do a choke tube installation, depends on how thick the barrels walls are. If you have either job done here, be sure the smith does it right and the point of impact doesn't change. As I understand it requires bushings in both ends of the barrel to keep the tooling concentric with the bore.

    Not familiar with that model however, I have recently dealt with this issue. For one (Remington 870) I simply purchased a new barrel that was compatible with steel shot, the other was a very old one from my father in law. This one I had a gunsmith bore out and refinish and re-blue. Can not remember what the cost of the bore was but the job overall was reasonable. Check with a local gunsmith to determine costs involved and go from there. It may be more cost effective to buy a new gun (rats eh?) than to get the work done. In my case it was more sentimental value than collector value being the reason to do the work.

    Look at Carlson Chokes. I bought one IC. Because the skeet club in Greenwood, only allowed steel shot.

    And they also make modified and full chokes that accepts lead, and steel shot. I'm sure they would make one for Beretta.

    interesting, I wondered about that don't hunt ducks anymore or upland
    now some places are steel shot only I hear so a newer gun like my mossy 88 would be okay
    for barrel change but what about like an old cooey ranger single shot break barrel or my old JC higgins
    to a smith I guess would cost more than the guns are worth but they were my uncle and grandfathers
    might be better to go buy a new Remy or Benelli semi if a guy wanted to take up bird hunting again

    Thanks for the replies so far.
    I have a name in Alberta that supposedly would mod. for screw on chokes, was hoping for something closer. I'm from Saskatchewan.
    Yesterday I did find a gunsmith in Sask. that will ream where the shot exits the shell and the choke for $125. My worry is that the barrel is suppose to be chrome lined and reaming removes some chrome and is hard to do. Gunsmith says they have done many, never had a problem (" knock on wood" ) and the barrel should last a long time since I will only be hunting geese and ducks.
    My thinking is that even for a screw on choke reaming would still be required where shot exits the shell.

    When you say "where the shot exits the shell" do you mean the forcing cone? Not sure why that would need to be done unless it's necessary for fixturing a bushing at the breech end. No matter what you do, the smith will be cutting into the chrome plating at the muzzle end. If he's putting in tubes, he must totally remove the old choke. If he's opening it up a bit he will remove a bit less, but he's still cutting into the chrome.

    No worried about barrel wear or corrosion with a bit of chrome gone. Literally millions of barrels out there without it.

    There's more to it than the choke. The forcing cone and the steel of the barrel matter too. Just opening the choke won't fix any of that. Buying a steel rated barrel will.
    Fortunately, steel(or non-lead) is only required for migratory birds in most Provinces. Isn't necessary for anything else. Putting on changeable chokes will make your shotgun far more versatile. Even with the long barrel.
    Where you are matters somewhat. Talk to Precision Arms in King City, Ont. (That's north of Steeles Ave in TO.) They're shotgun specialists.

    I believe forcing cone is what gunsmith said required reaming in addition to choke. He said that barrels for this old of a Beretta were had to find.
