Description
When you're setting up for a mature gobbler that's hanging up at 45 yards, Federal Heavyweight TSS is exactly what you need. These 3.5-inch shells pack 2-1/4 ounces of tungsten super shot in a #7 size, delivering around 424 pellets downrange at 1200 fps. That's roughly twice as many pellets as you'd get from a lead #5 load of the same weight, and every single one of them hits with more energy retained at distance.
What makes this load special isn't just the pellet count, it's the density. Tungsten runs 18 grams per cubic centimeter, which is 22 percent denser than standard tungsten and 56 percent denser than lead. In practical terms, this means a #7 tungsten pellet hits as hard as a #5 lead pellet, so you get pattern density and penetration without stepping up to huge shot sizes.
The FLITECONTROL FLEX Advantage
Federal engineered the FLITECONTROL FLEX wad specifically for tight patterns through standard and ported turkey chokes. The rear-braking design stabilizes your pattern from the muzzle all the way out, and the full-length wad prevents those hard tungsten pellets from ever touching your bore, which protects your barrel from wear. Advanced buffering material keeps everything in place through the shot column, so you get consistent patterns every time.
Real Performance at Real Range
These load patterns densely enough that you can make ethical shots well beyond what traditional loads allow. Pattern testing shows these shells putting well over 100 pellets in a 10-inch circle at 40 yards through most turkey chokes, which is exactly what you're looking for in a gobbler's vitals zone. The velocity and pellet density hold together so well at distance that you've got genuine range without sacrificing lethality.

Frequently Asked Questions
What's the difference between #7 and #9 shot in TSS loads?
#7 gives you larger, heavier pellets that retain more energy at distance and work better for 40+ yard shots. #9 puts more pellets downrange in a tighter pattern and works great for close to medium range in tight cover. Most hunters choose #7 for the standard 12-gauge 3.5-inch load because that extra size matters when you're pushing range limits.
Will Federal Heavyweight TSS work through my turkey choke?
The FLITECONTROL FLEX wad is designed to work with both standard and ported turkey chokes. You don't need to buy anything special. Pattern it before season to see how your specific gun shoots, since every shotgun is different.
How does tungsten compare to lead for turkey hunting?
Tungsten is significantly denser, which means smaller pellets hit as hard as larger lead shot. These #7 tungsten pellets perform like lead #5s, so you get much higher pellet counts in your pattern without sacrificing energy at range. That's why TSS has become the go-to for hunters who want extended-range capability.
What makes this different from Federal's other turkey loads?
Heavyweight TSS uses the densest tungsten-alloy available (18 g/cc) paired with advanced buffering and the FLITECONTROL FLEX wad for maximum pattern density and consistency. It's purpose-built for extreme-range turkey hunting where pattern quality and long-range performance matter most.
