Winchester Last Call TSS ammunition brings tungsten shot technology to 20-gauge waterfowl hunting in a 3-inch, 1-ounce load with #7 shot. If you've been curious about tungsten for waterfowl but thought it was only available in 12-gauge, this load makes the switch accessible without stepping up in gun size. Tungsten delivers significantly more downrange energy and penetration than traditional steel shot in the same payload weight, which matters when you're threading shots through cover or at distance.
The real advantage here is pattern density. A 1-ounce tungsten load throws roughly 40% more pellets downrange than a comparable steel payload, concentrating your shot column in a tighter, deadlier pattern. That means a wider effective kill zone and fewer wounded birds lost to the marsh. The sealed wad and primer are engineered to handle wet conditions—rain, snow, and spray won't compromise reliability the way moisture can compromise conventional ammunition.
Winchester recommends pairing these loads with a light modified choke or less constriction to optimize patterns. The 18 G/CC density of the tungsten shot gives you the ballistic benefits without requiring you to completely re-tune your gun setup.

Winchester recommends using a light modified choke or less constriction to achieve optimal patterns with these loads. The density of tungsten shot patterns differently than steel, so tighter constrictions than you'd normally use for steel may over-tighten your pattern.
Tungsten delivers over 50% more payload energy and 1.8 times greater penetration than an equivalent weight of #2 steel at typical waterfowl ranges (30-inch circle at 40 yards). The 1-ounce tungsten load also throws approximately 40% more pellets than a comparable steel load, creating a denser pattern and wider kill zone.
Yes. The sealed wad and primer are specifically designed to resist water penetration and provide reliable performance in wet conditions, including rain, snow, and spray typical of duck and goose hunting.
Each case contains 10 boxes of Winchester Last Call TSS ammunition, with 10 rounds per box, for a total of 100 rounds.
