Description
HEVI-18 TSS Turkey puts serious distance in your turkey hunting. These 12-gauge shells pack a 2-ounce payload of ultra-dense tungsten pellets rated at 18 g/cc density, roughly 48 percent denser than lead. That density translates to harder hits and tighter patterns that stay lethal well past where traditional lead loads run out of steam.
Why #7 Shot Works for Extended Range
With #7 HEVI-18 pellets, you get fewer rounds per ounce compared to #9 loads, but each pellet carries noticeably more individual energy. This shot size is the go-to for hunters expecting ranges from 30 to 50 yards and wanting reliable penetration on tough birds. The tradeoff is worth it if your hunting situations call for punch over pure pattern density.
Precision Pattern Engineering
Every shell features HEVI-Shot's sealed spherical buffer system, which reduces friction as pellets move through your choke. That design choice delivers the incredibly tight patterns this load is known for. Add in the crimp-seal resin that holds everything in place, and these shells maintain shot integrity shot after shot, regardless of weather or how they rattle around in your vest during a long morning in the woods.
Velocity and Performance
Loaded to 1250 fps, these shells push that dense payload at velocities that keep the tungsten working hard downrange. The combination of density, velocity, and the buffering system gives you patterns that hold together longer than what you'd get from comparable lead loads, meaning more pellets stay in the lethal zone at distance. Five rounds per box lets you pattern your gun and get ready without overbuying.

Frequently Asked Questions
How does HEVI-18 compare to lead or steel turkey loads?
HEVI-18 uses tungsten alloy pellets rated at 18 g/cc density, making them nearly 48 percent denser than lead. This extra density lets you drop multiple shot sizes while keeping the same energy and penetration. You get more pellets per ounce, tighter patterns, and extended effective range compared to traditional lead turkey loads.
What distance should I expect to hunt effectively with the #7 shot in these shells?
The #7 shot in this HEVI-18 load is designed to be effective from about 25 to 50 yards, with some hunters successfully reaching out to 60 yards under ideal conditions with proper choke selection. The larger pellet size offers better penetration than #9 shot at extended ranges, though you sacrifice some pellet count per pattern.
Do these shells work with standard turkey chokes?
HEVI-18 shells work with standard turkey chokes, but many hunters see improved patterns with a dedicated TSS-specific choke tube. Because tungsten is much harder than lead, quality TSS chokes are designed with specifications optimized for how these dense pellets perform through the constriction.
What makes the spherical buffer system important?
The sealed spherical buffer reduces friction between pellets as they travel down the barrel and through your choke. This friction-reducing design is key to HEVI-Shot's reputation for exceptionally tight, consistent patterns. The crimp-seal resin keeps the buffer secure inside the shell, so it performs reliably through multiple shots and rough handling.
