use lead only steel chokes are specified on the choke as steel of lead shot
Yes. Lead shot may be safely fired from a shotgun that is made for steel shot. Problems arise when you fire steel shot from an older shotgun that is made for lead shot only- the barrel is softer metal, and make be scratched by the steel shot.
That will depend on whether the choke tube is rated for steel shot or not.
You can use steel shot with a choke anywhere from cylinder to modified, i wouldn't recommend using steel with a improved modified or a full choke.
The use of steel shot doesn't directly have anything to do with a "Belgium" made shotgun barrel. The only significance is that the gun/barrel was manufactured in in Belgium. The problem with steel shot can be a problem with any shotgun made before the steel shot came into use. The problem has to do with the choke. The use of lead shot shells didn't pose a problem because lead is soft compared to steel. The choke is a constriction at the end of the barrel that can change the shot pattern of the shot shell pellets. The inside diameter of a typical 12 gauge shotgun is about .726 +or- a few thousandths. The constriction of a full choke is about .030 thousandths tighter with a diameter of about .696 Steel shot doesn't compress the same a lead and as a result can damage an older gun not designed for steel shot. Most older guns can handle steel shot if they have a more open choke for example an Improved Cylinder choke. Another alternative is to use another non-lead alternative ie. bismuth. Even with new guns you shouldn't use Full Choke with steel. Modified Choke will generally produce relatively tight patterns with steel. If the gun has some collector value, don't take a chance. If you are determined to hunt with it and want to shoot steel shot, see a gun barrel specialist like Ballistic Specialties in Batesville Arkansas. They can do anything just about with a shotgun barrel.
That will depend on whether the choke tube is rated for steel shot or not.
Unless they have been rebarreled, or a newer choke tube installed, no. The Sweet 16 was made at a time when all shot were lead, and the barrels are softer steel. Steel shot will damage the barrel.
Yes. Please note that is lead shot SIZE BB, and not the steel balls shot by air rifles.
If it was made to shoot steel shot and has interchangeable chokes.
Depends on the choke, load, barrel length and who made the loaded round.
Check the owner's manual, or check with Mossberg customer service. Unless the choke is rated by the maker for steel shot, not good to do.
NO. Early shotguns have softer steel barrels, and are not rated for steel shot. It will damage the choke of the shotgun.
Depends on the load and what the maker of the choke/shotgun say.
