Migra Ammunitions M12SB46 12 Gauge 3" 1 1/2 oz 4/6 Shot Hunting Ammo - 25 Rounds per Box, 10 Boxes per Case

The Migra Ammunitions M12SB46 is a 12 gauge shotshell load built for hunters who need reliable, effective shot patterns across varied game and conditions. This 3-inch shell carries a 1½ oz payload in a 4/6 shot combination, offering the flexibility to handle everything from upland birds to waterfowl depending on your distance and target. Whether you're working a field or a marsh, this ammunition delivers the ballistic balance of mixed pellet sizes in a case quantity that keeps you stocked through a full season.

Steel shot loads like these give you a non-toxic option that meets regulations in many regions and works in most modern shotguns rated for steel. The 4/6 shot split means you get both the pattern density of larger pellets and the velocity boost that smaller shot brings—a practical compromise for hunters who don't want to swap loads mid-day. At 25 rounds per box and 10 boxes per case, you're looking at 250 rounds of consistent, field-proven ammunition.

Migra Ammunitions builds their loads to run clean and cycle smoothly across semi-auto, pump, and break-action shotguns. The combination load philosophy behind this shell reflects real-world hunting: rarely does one shot size cover every scenario, so pairing them gives you a single load that stays relevant from first light to last.

Frequently Asked Questions

What does 4/6 shot mean, and why would I choose it?

The 4/6 designation means this shell contains a mixture of size 4 and size 6 pellets. Size 4 shot carries energy farther and penetrates deeper, making it effective on larger game or at longer distances; size 6 shot produces denser patterns and generates flatter trajectories. By combining them in one load, you avoid having to switch shells between shots and gain a balanced pattern that works across a wider range of hunting scenarios.

Is this ammunition suitable for my semi-auto shotgun?

This Migra steel shot load is designed to cycle in most modern shotguns rated for steel, including semi-automatics, pump-actions, and break-actions. Always verify your shotgun's manual or markings to confirm it accepts steel shot and is rated for 3-inch magnum loads before use.

What's included in a case order?

One case contains 10 boxes, with 25 rounds per box, for a total of 250 rounds. This quantity is ideal for serious hunters planning an extended season or regular range practice.

Are there any hunting regulations I should know about with steel shot?

Steel shot is non-toxic and required in many regions, particularly for waterfowl hunting and in certain wildlife areas. Always check your local and state hunting regulations to confirm what ammunition types are legal for your intended game and location.
