Probably not recommended, but I have had the same choke tube in the gun for almost 20 years. It is the old style Mossy Oak finish and if you saw it, you would see it has been used for lots of things a shotgun should never be used for. I shoot about three to five cases of steel, several cases of lead rounds and even slugs for deer through it each year. It still patterns well, never lets me down and it kills, so that is what I stick with.
Many of the new guns come with full chokes for steel. Some of the aftermarket chokes are made with tight constrictions for steel. Each choke should be checked to see if it is steel compatible before using it with steel. Full for steel is fairly common for ducks here in AR, even in the timber where it is close quarters shooting. It is not fun to chase cripps through flooded timber.
