Migra Ammunition (part no. M410B6) loads this .410 bore shell with #6 bismuth shot in a 3-inch hull at 1460 fps, giving hunters a lead-free option that’s still soft enough to shoot safely through older or fixed-choke shotguns that lead-free steel shot could damage. Migra Ammunition builds its bismuth line specifically for that niche: shooters who need non-toxic shot but own a gun with a tighter choke or older barrel steel not rated for hard steel shot. It’s a purpose-built option for .410 hunters who fall into that category. In shotgun shells built around bismuth technology, this is a specialized niche load.
