Federal Premium Hevi-Bismuth Ammunition 20 Gauge Non-Toxic Shot

Federal Premium Hevi-Bismuth 20 gauge ammunition delivers genuine non-toxic performance for hunters working both upland and waterfowl without the velocity penalties you get from plain steel. Built around HEVI-Bismuth pellets at 9.6 g/cc density—22 percent denser than steel—this load puts more energy downrange and patterns tighter than comparable steel loads of the same shot size, which matters when you're counting on clean, ethical kills in the field.

The secret is the FLITECONTROL FLEX wad, a rear-deploying design that keeps your pattern consistent and efficient whether you're shooting a vintage heirloom or a modern gas gun, ported or not. Bismuth itself is softer than steel and tungsten, so it cycles reliably in a wider variety of shotgun actions and won't wear out your barrel the way harder alternatives do. The pellets themselves are alloyed and cast right here in the USA, which means tight quality control and the kind of consistency serious shooters expect.

If your local waters or public lands require non-toxic shot and you've been frustrated by lackluster performance from standard alternatives, Hevi-Bismuth bridges that gap. You're not making a compromise—you're making a choice that honors the game and the gun.

Frequently Asked Questions

Will Hevi-Bismuth work in older shotguns?

Yes. Bismuth is softer than steel and tungsten, making it safe and effective in both classic and modern shotguns without excessive wear. The FLITECONTROL FLEX wad is also designed to work in both newer and vintage actions.

Why is Hevi-Bismuth denser than steel?

At 9.6 g/cc, Hevi-Bismuth pellets are 22 percent denser than steel, meaning they retain velocity and energy better downrange and provide higher pellet counts than steel loads performing at comparable levels. This translates to tighter patterns and more consistent, ethical kills.

What's the difference between the FLITECONTROL FLEX wad and a standard wad?

The FLITECONTROL FLEX is a rear-deploying design that creates more consistent and efficient patterns, whether you're shooting through ported or non-ported chokes. This consistency is key to reliable performance across different shotgun setups.

Where can I use Hevi-Bismuth ammunition?

Federal Premium Hevi-Bismuth is a non-toxic shot option. Check your local regulations—bismuth is approved for waterfowl and upland hunting in many areas where non-toxic shot is required, but specific rules vary by region and season.
