Winchester Last Call TSS is a premium tungsten shotshell designed for waterfowl hunters who demand reliable, long-range performance in demanding conditions. This 12-gauge, 3-inch load carries 1¼ ounces of #9 tungsten shot—a denser, harder alternative to traditional steel that delivers significantly more stopping power per pellet. If you're serious about duck and goose hunting and need ammunition that patterns tight and penetrates deep, Last Call TSS is built to deliver shot after shot.
The real advantage of tungsten lies in its density: at 18 grams per cubic centimeter, it allows Winchester to pack substantially more effective payload energy into a standard shotshell compared to steel shot of the same size. More pellets in the pattern means a wider effective kill zone at range—critical when you're working birds that are already wary or when conditions push your shots to the outer edges of your gun's capability. The sealed wad and primer design keeps moisture out, ensuring reliable ignition and consistent performance even after hours in wet blinds or rough weather.
Winchester recommends pairing this load with light modified choke tubes or less constriction to optimize the dense pattern potential of the tungsten payload. The box contains 10 shells; this listing is for a case quantity of 10 boxes (100 rounds total). Whether you're hunting over decoys at first light or taking pass shots late in the day, Last Call TSS rounds perform when it matters.

Winchester recommends light modified choke tubes or less constriction to achieve optimal patterns with this tungsten load. Tighter chokes than light modified may result in overly dense patterns.
Tungsten is significantly denser than steel, allowing Winchester to deliver more payload energy and greater penetration with the same pellet count. The #9 tungsten shot provides substantially more pellets in the pattern compared to equivalent steel loads, maximizing your effective kill zone.
Yes. The sealed wad and primer design provides excellent water resistance and reliable performance in harsh weather and wet blind conditions.
