When federal waterfowl zones mandate non-toxic shot and you’re running a 20 gauge over flooded timber or rice fields, Winchester Xpert High Velocity 20 gauge steel shot ammo puts 7/8 oz of #4 steel downrange at 1500 fps from a 3″ shell. This load balances velocity with pellet count — #4 steel delivers approximately 135 pellets per shell, sufficient to anchor ducks inside 35 yards while maintaining energy on teal, gadwall, and pintail. The wad design protects smoothbore barrels from steel-on-steel contact, a concern in older shotguns not rated for steel shot. Winchester manufactures this ammunition in the United States with non-corrosive Boxer primers and reloadable hulls, though steel shot reloading requires specialized equipment and is less common than lead reloading.
Built for the Box
The 3″ 20 gauge hull accommodates the 7/8 oz steel payload without excessive pressure, and the 1500 fps muzzle velocity sits in the middle of the modern steel shot range — fast enough to flatten trajectories but not so fast that patterns blow open at 25 yards. The 6-point star crimp ensures consistent ignition and gas seal. Steel shot does not deform like lead, so pellets maintain spherical shape in flight, improving pattern uniformity but requiring tighter chokes than equivalent lead loads. For #4 steel, Modified choke is the typical starting point; Full choke can over-constrict and create donut patterns with blown centers.

This load ships as a 250-round case (10 boxes of 25 shells) and qualifies for volume pricing. Steel shot is federally mandated in all U.S. waterfowl hunting zones; verify state-specific non-toxic shot regulations, as some states permit bismuth or tungsten alloys but restrict other materials.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Treat every firearm as if it is loaded. Keep the muzzle pointed in a safe direction. Keep your finger off the trigger until ready to fire. Be certain of your target, backstop, and what lies beyond.
- Verify that your shotgun barrel is rated for steel shot before firing. Older barrels marked “lead shot only” can be damaged by steel pellets.
- Steel shot requires different choke settings than lead. Consult your shotgun manual for recommended choke constrictions to avoid barrel damage or pattern disruption.
