Description
Federal Premium Prairie Storm FS Steel delivers the kind of consistent performance upland hunters need when the birds are fast and the pressure is on. This 3-inch 20 gauge load pairs a rear-opening FLITECONTROL FLEX wad with a mixed payload of standard steel and FLITESTOPPER pellets, a combination designed to generate full edge-to-edge patterns from any upland choke.
Prairie Storm FS Steel Pattern Performance
The real story here is what happens downrange. Testing shows this load puts more than 75 percent of its pellets in a 30-inch circle at 40 yards, while producing energy levels comparable to the lead loads many folks have hunted with for years. The 7/8 ounce payload travels at 1500 fps, fast enough to maintain velocity on tougher targets but not so hot that it beats up your gun or your shoulder unnecessarily. The FLITESTOPPER pellets feature a distinctive cutting ring that creates larger wound channels than standard round shot, meaning better results on the birds you do connect with.
Designed for Upland Chokes
The FLITECONTROL FLEX wad opens from the rear, with fins that reliably deploy regardless of the pressure behind them. This design works seamlessly through standard upland chokes as well as ported ones, so you're not limited in your barrel choices. That flexibility matters when you're trying to match your gun to your hunting situation.
These loads come in 25-round boxes, giving you plenty to pattern your gun and run a solid morning or afternoon in the field. For hunters who want steel shot performance without compromising on pattern quality or reliability, this is a load that will work.

Frequently Asked Questions
What makes FLITESTOPPER pellets different from standard steel shot?
FLITESTOPPER pellets have a distinctive cutting ring around their circumference that creates larger wound channels on impact compared to round pellets. This ring also causes the pellets to naturally drift slightly away from the center of the pattern, which helps distribute the shot more evenly across your target while transferring energy more efficiently.
Can I use Prairie Storm FS in any choke tube?
The FLITECONTROL FLEX wad is designed to work through both standard and ported chokes, so you have good flexibility with your barrel setup. However, upland chokes are the intended application for these loads, and they'll deliver their best performance when used that way.
How does the pattern of this 20 gauge load compare to lead ammunition?
Federal engineered the Prairie Storm FS to deliver energy similar to popular lead loads while maintaining the advantages of steel shot. The load puts more than 75 percent of pellets in a 30-inch circle at 40 yards, with the FLITESTOPPER pellet mix helping to ensure consistent, dense patterns across the board.
Is this load suitable for pheasant hunting?
Yes. Federal specifically designed Prairie Storm FS with upland birds in mind, and the combination of velocity, shot size, and pattern density makes it well-suited for pheasants and other tough, fast-flying targets at typical upland hunting distances.
