Hevi-Shot Hevi-XII 20 Gauge 3" Non-Toxic 12 Density Shot Ammunition

Hevi-Shot Hevi-XII 20 gauge 3" non-toxic ammunition brings tungsten-based performance to a 20 gauge shell, giving you significantly denser pellets than steel without the regulatory restrictions. These loads use Hevi-Shot's original 12 g/cc tungsten composition—53.8 percent denser than steel—which means you're packing more striking energy downrange and tighter patterns from every shot. Whether you're hunting upland birds, waterfowl (where non-toxic is required), or simply prefer lead-free ammo, Hevi-XII delivers the terminal performance hunters expect from tungsten at a gauge many of us prefer to shoulder all day.

The density advantage translates to real-world benefits: you can drop down three shot sizes and maintain lethal energy, or stick with your normal shot size and gain roughly 28 percent more pellets in the pattern. High velocity loads keep energy levels up at distance, and Hevi-Shot specifically engineered these for reliable performance in cold weather. Because tungsten is substantially harder than steel, pellet integrity is better too—less deformation means cleaner, more consistent patterns.

Hevi-XII is purpose-built for hunters who need non-toxic compliance or simply want the ballistic edge tungsten provides. The 3" shell format gives you payload capacity without requiring a dedicated mag-fed or semi-auto gun; standard 20 gauge pumps and over-unders handle it just fine. Load up a box and you'll immediately feel the difference—these shells have real weight, and that density works in your favor from the moment they leave the barrel.

Frequently Asked Questions

Will Hevi-XII work in my standard 20 gauge shotgun?

Yes. Hevi-XII 3" shells are loaded to standard pressure and function in any 20 gauge shotgun rated for 3" ammunition—pumps, semi-autos, and over-unders all handle them without issue.

Why choose tungsten over steel for non-toxic hunting?

Tungsten is substantially denser than steel, which means each pellet carries more energy at distance. You get the same or better performance with fewer pellets, or better patterns with the same shot size. Steel requires larger pellets to match tungsten's energy, which reduces pellet count and pattern density.

Can I use a smaller shot size with Hevi-XII?

Yes—Hevi-Shot specifically states you can drop three shot sizes and maintain lethal performance thanks to the density advantage of tungsten. This means smaller patterns and less shot spread, which can be valuable for longer-range or precision hunting situations.

Are these loads compliant for waterfowl hunting?

Hevi-XII is 100 percent non-toxic, which meets federal and state waterfowl hunting requirements. Always check your local regulations, but non-toxic ammunition is legal for all migratory bird hunting.
