Description
The HEVI-18 TSS delivers everything serious turkey hunters demand: range, lethality, and consistent performance in the field. Loaded with 2-1/4 ounces of ultra-dense 18 g/cc Tungsten Super Shot, this 3.5-inch magnum shell gives you more smaller pellets in a tighter pattern compared to traditional lead, without sacrificing any downrange energy.
What Makes HEVI-18 TSS Different
Tungsten is significantly denser than lead, which means you get roughly twice the pellet count with smaller shot sizes. Those 2-1/4 ounces of #9 tungsten shot contains hundreds more pellets than you'd load into a lead shell, all packed into patterns that hold together farther than anything else on the market. The friction-reducing spherical buffer keeps pellets from stripping away as they travel, so your pattern stays lethal well beyond 50 yards when paired with the right choke.
Performance at Range
Chrono'd at 1250 feet per second, the HEVI-18 maintains velocity and energy at extended distances where lead runs out of steam. Real-world testing shows these shells deliver 100+ pellet strikes in a 10-inch circle at 40+ yards, the benchmark for clean turkey harvests. At 20 yards, the pattern tightens up dramatically, creating that dense core you need for confident head and neck shots.
Built for Reliability
The sealed spherical buffer stays put with a crimp-seal resin that resists damage during transport and handling. The thicker base-wad and hotter primer work reliably in semi-automatic shotguns through all kinds of weather. Plastic casing handles the pressures of TSS loading without issues. This shell comes in boxes of 5 rounds, sized for turkey season packing and field work.

Frequently Asked Questions
What shot choke should I use with the HEVI-18 TSS?
Extra-full or turkey-specific chokes work best, ideally in the .660 to .670 range for 12 gauge. TSS patterns so densely that standard full chokes might give you patterns that are too tight at 20-30 yards. Pattern your gun with your setup before opening day to find the sweet spot for your particular shotgun.
Is the HEVI-18 non-toxic?
Yes, tungsten is completely non-toxic, making these shells suitable for all hunting areas including those with lead shot restrictions. The tungsten-iron-nickel alloy performs like lead but without environmental concerns.
How does #9 shot work for turkey hunting?
The extreme density of TSS allows smaller pellets to carry the same energy as much larger lead pellets. Number 9 tungsten delivers more pellets per shell than traditional turkey loads, creating denser patterns with more chances to connect on the vitals. At extended ranges, this translates to tighter, more lethal patterns.
Will my shotgun handle HEVI-18 loads safely?
You need a shotgun rated for 3.5-inch magnum loads. Check your shotgun's manual to confirm it handles 3.5-inch shells, as not all 12 gauges do. The dense tungsten creates normal pressure levels, but verify compatibility before loading up.
