The HEVI-18 TSS steps up what's possible with a .410 bore. Using ultra-dense tungsten pellets at 18 g/cc, these shells deliver the kind of downrange energy and pattern density traditionally reserved for larger gauges. The #7 shot size strikes a balance between pellet count and penetration, making it effective at ranges that would be a stretch for traditional lead ammunition. Pair that density advantage with the light recoil profile of the .410, and you've got a genuinely capable turkey gun that doesn't beat you up.
The real difference is in the friction-reducing spherical buffer. This isn't just packing material. It helps the pellets flow consistently through your choke without distortion, which translates to tighter, more reliable patterns. The buffer stays put thanks to HEVI-Shot's unique crimp-seal resin, and it holds up to a full season of bouncing around in your turkey vest without coming loose.
The 13/16 ounce payload at 1090 fps means you're getting solid pellet counts in a compact shell. That matters when you're building patterns at 35, 40, even 45 yards. Since tungsten is about 48 percent denser than lead, the smaller #7 pellets carry energy downrange like much larger lead shot would, which opens up ethical hunting opportunities that simply weren't realistic with traditional .410 turkey loads.
These shells are loaded with a thicker base-wad, hotter primer, and clean-burning propellants so they perform reliably in any weather. Whether you're hunting out of a blind in November cold or early season spring when humidity is high, they ignite consistently. The non-toxic designation means you can use them anywhere turkey hunting is legal, without worrying about shot material restrictions.
The 18 g/cc density pellets make #7 TSS carry more energy downrange than larger lead shot would, giving you higher pellet counts and tighter patterns at extended range. This density advantage is what transforms a .410 from a close-range gun into something capable at 40+ yards.
Yes, these shells are specifically designed for semi-automatic shotguns. The thicker base-wad, hotter primer, and clean-burning propellants ensure reliable cycling and consistent ignition across different weather conditions.
The friction-free buffer allows pellets to flow smoothly through your choke without deforming, which creates tighter, more consistent patterns. It's sealed in the shell with a special resin so it stays put throughout the season and won't rattle loose in your vest.
HEVI-18 TSS is non-toxic tungsten, which complies with non-toxic shot regulations. However, ammunition regulations vary by location, so check your local regulations before purchasing.
