I`ve been watching the auctions and a question has formed,having originally been looking to upgrade my mod.fixed choke 870 with a screw in choke barrel.The primary reason i would want to do this would be for goose/duck hunting so would want a full choke. I have seen alot of 30 in fixed full choke barrels being sold and was wondering about the choke design....would a factory fixed choke have a more gradual taper to the choke? in my mind(right or wrong) I would think that a more gradual choke would lead to a tighter pattern than a short screw in choke,especially since i see aftermarket turkey chokes that are extended.
also are these factory barrels ok with loads needed for goose/duck.specifically steel and the like?

I can't answer your question on the fixed choke lenght factor. However, if you have a Rem choke system or similar, there are all kinds of aftermarket choke tubes on the market specifically for high performance with steel, hevi shot, etc. Terror, Wad wizzard, and others.

The proof is in the paper when you pattern. Steel patterns tighter as a general rule and has a shorter shot string.

Most factory barrels in the last 20~25 years should be good for steel/hevi if in doubt, see a qualified gun smith.

I'm not sure you need a new barrel. As Sx2 indicated steel shot patterns tighter than lead. It is generally recomended to drop a size or two in choke when shooting steel especially in the larger shot sizes such as BB and larger. In all likelyhood your "modified "choke is throwing a full choke equivalent when shooting steel. Personally I think Modified is even a bit tight for steel and prefer to use a modified or modified/improved. Remember that steel does not have the energy and/or range that lead does. Many consider 30 yards to be the maximum EFFECTIVE range. Not to say tha birds can't be dropped further out but a tight pattern is no good if the pellets don't penetrate. A full choke with steel may turn the close ones to hamburger but fail to drop the long ones. Pattern your gun and see how it does.

Forgot to mention: since steel is lighter a 1 1/8 oz load of steel contains considerably more pellets than a 1 1/8 oz load of lead giving you a more dense pattern so in effect you gain not only a tighter pattern but a more dense one as well. Put it this way take your current pattern with lead, reduce it a couple inches,include the pellets from the deducted area and add 7-10% more pellets to account for the additional steel pellets. If that is the pattern you are looking for stick with the modified choke. There is a point of no return with steel because of it's hardness. Too tight a choke and you start blowing your patterns.

Bismuth is a non tox lead substitute that is almost as dense as lead. The nice thing about it is it is not harmfull to the steel in older gun barrels. I buy one box per year to shoot through a 1940's vintage 16 guage I have.

Tungsten or a tungsten nickle mix is denser that steel but just as hard as steel. The pellets cary more energy but can be damaging to older guns.

so i guess you choke bismuth the same as lead? and tungsten like steel?

As a recommended stater point yes.

What dakotashooter said is true as well.
