Description
The Fiocchi 1235ST1 Flyway Steel 12ga shell, item 1235ST1, is a 12 gauge, 3-1/2 inch waterfowl load with 1 3/8 oz of #1 plated steel shot at a rated 1,470 fps. Some retailers list it as Fiocchi Speed Steel; Fiocchi now catalogs it in its Flyway Series.

Fiocchi 1235ST1 Flyway Steel 12ga Overview
Long magnum hulls exist for one reason: more payload at useful speed for big birds. This 3-1/2 inch shell carries a heavy 1 3/8 ounce charge of #1 shot, a size many hunters choose for Canada geese over decoys and for big ducks when birds hang at the edge of range. Fiocchi uses plated steel, which helps resist corrosion and keeps pellets flowing smoothly through the choke. The shells are loaded with water-resistant components designed for the wet, cold conditions of a waterfowl blind, and they are made to deliver consistent velocity shot after shot.
Shot Size and Game
Number 1 steel is a versatile big-bird size. It sits between BB and 2 shot, offering more pellets than BB while retaining enough energy for geese at moderate range and large ducks at longer distances. Pattern your gun with this load before the season, because steel patterns differently than lead and every choke and barrel combination reacts a little differently.

Speed and Steel
At a rated 1,470 fps, this is a fast steel load. Steel is lighter than lead, so it loses velocity sooner; starting faster helps pellets arrive with more energy. Even so, keep shots at reasonable distances, typically inside 40 to 45 yards, for clean, ethical kills. Lead your birds a little less than you would with slower loads, and practice on clays with similar speeds before the season.
Choke and Barrel Notes
Steel shot does not compress like lead, so it patterns tighter through a given choke. Most makers recommend improved cylinder or modified chokes with steel, and some older barrels and full chokes are not rated for steel at all. Check your gun manual or the markings on your choke tubes before shooting steel, and never fire steel through a choke marked lead only. Older fixed-choke guns and fine double guns should be checked by a gunsmith first.

Chamber and Recoil
Fire this shell only in 12 gauge shotguns chambered for 3-1/2 inch shells. Do not use it in a gun with a shorter chamber. A 3-1/2 inch 12 gauge steel load produces heavy recoil. A gas-operated semi-auto, a good recoil pad and proper gun fit make a big difference over a long morning. If you shoot a lightweight pump, consider whether a 3 inch load would serve you just as well.
Legal Notes
Federal rules require non-toxic shot for migratory waterfowl hunting across the United States, and steel is the most common non-toxic option. Many states also require non-toxic shot on certain public lands and wildlife areas for other game. Always check your state regulations, bag limits and any plug requirements before you hunt.
Storage and Care
Store shotshells in a cool, dry place in their original boxes. Steel loads used in the blind often get wet; let them dry before storing, and discard any shells with swollen or damaged hulls.
