Description
The BioAmmo Rex Steel 12 GA 1 oz 7 Shot (BioAmmo part BRS2870) is a non-toxic load for dove hunting and clay shooting. It puts 1 ounce of #7 steel shot in a 2-3/4 inch shell, uses a biodegradable hull and wad, and is listed by retailers at about 1,280 fps. Each box holds 25 rounds.

Why Choose the BioAmmo Rex Steel 12 GA 1 oz 7 Shot
More public dove fields, wildlife areas and some shooting ranges now require non-toxic shot. Non-toxic dove shells like this one let you comply with those rules while still using a familiar 1 ounce payload.
BioAmmo goes a step further by building the hull and wad from plastic free, biodegradable materials. On a busy dove field or a clay range that sees thousands of shells each season, that difference adds up.
The #7 steel pellet size is a good balance for doves and clays, since steel is lighter than lead and a slightly larger pellet helps retain energy.
Using the BioAmmo Rex Steel 12 GA 1 oz 7 Shot
Steel patterns tighter than lead through the same choke. Improved cylinder or skeet chokes rated for steel are good starting points for dove and close clays. Avoid tight full chokes and older fixed chokes not rated for steel shot.
As a steel target load, it is also useful on ranges near water or on public lands that prohibit lead. Recoil is moderate and comparable to a standard 1 ounce target shell.
Always confirm that your shotgun is rated for steel shot, particularly with vintage doubles. Store biodegradable shells in a dry place, since the components are designed to break down over time when exposed to moisture.

Who Should Buy This Load
Dove hunters on public land, clay shooters at lead-restricted ranges and anyone who wants a cleaner lead free shotshell will find this BioAmmo load a practical choice.
Steel shot has less energy than lead at the same size, so keep shots at reasonable distances on doves. For heavy hunting in lead-legal areas, a lead dove load may pattern and hit harder at range.

Pick up your hulls when you can. Even biodegradable components take time to break down, and a clean field keeps landowners and range managers happy.
Pattern the load at 25 yards to see how steel prints through your chokes before opening day.
Who it is for: 12 gauge dove hunters and clay shooters who need or prefer non-toxic steel with biodegradable components. Follow all federal, state and local regulations when using this ammunition.
