Migra Ammunitions M12S13 12 Gauge 3" 1 1/4 oz Hunting Shotgun Shells - 25/Box, 10/Case

Migra Ammunitions M12S13 12 gauge 3" shotgun shells are purpose-built for hunters who need reliable, pattern-consistent loads across different game and conditions. Loaded with 1 1/4 oz of shot at 1430 fps, these steel shells combine a dual shot-size formula—mixing No. 1 and No. 3 pellets—to deliver denser patterns and more effective energy on target. That engineered shot combination is the core advantage: instead of relying on a single size, you get the ballistic benefits of two, reducing the gaps in your pattern and improving your odds in the field.

These aren't generic bulk shells—Migra's formula eliminates fillers and focuses on bulk density uniformity, which translates to shot strings that stay together longer and print tighter on the board. Whether you're working ducks, geese, or upland birds, consistent patterns mean fewer clean misses and more confident follow-ups. The 3" hull gives you that extra payload capacity without jumping to a 3 1/2" magnum, keeping recoil manageable while maximizing your load density where it counts.

Sold in convenient 25-round boxes, with a 10-box case option for regular hunters and club shooters. Load these and you'll appreciate the difference a thoughtfully engineered shell makes when the moment arrives.

Frequently Asked Questions

What game are these 12 gauge shells designed for?

The M12S13 is engineered as a hunting load. The dual shot-size formula and pattern characteristics suit waterfowl (ducks and geese) and upland game where consistent, dense patterns improve your success rate.

Why mix two shot sizes in one shell?

The combination of No. 1 and No. 3 pellets is designed to fill gaps and maintain denser patterns downrange compared to single-size loads. More pellets in your pattern means more opportunity for effective strikes on moving targets.

Are these steel shot loads?

Yes—these are steel shotgun shells, appropriate for waterfowl hunting and other applications where steel is required or preferred.

How are these shells packaged?

Each box contains 25 rounds. You can purchase a single 25-round box or order a full 10-box case (250 rounds total) for regular shooters and clubs.
