Description
Sellier & Bellot built their reputation over nearly two centuries by producing ammunition that works when it matters. The SB12BR breaching load carries that legacy forward with a specialized design focused on controlled performance at close range.
What makes breaching rounds different is their engineering. Rather than traditional buckshot or slugs, this load uses a polymer shot construction that's specifically designed to destroy its target and then break apart. That means reduced ricochet risk and less unpredictable secondary effects compared to conventional shotgun loads. The lighter 1/2 ounce payload gives you the stopping power you need while maintaining precision and control in tactical or home defense scenarios.
The SB12BR's Velocity and Energy
Running at 1575 feet per second, these rounds deliver consistent energy for breaching purposes without excessive recoil. The 2-3/4 inch shell length works in most standard 12 gauge shotguns, so you won't need specialty equipment. Each box contains 10 rounds, with cases organized as 25 boxes per case for those who want to stock up.
Building Trust Over Time
Sellier & Bellot ammunition is trusted by law enforcement, military, and competitive shooters worldwide. The company manufactures to CIP specifications using non-corrosive primers and clean-burning powder. The brass cases are reloadable, and the quality control that goes into every round means you get predictable performance shot after shot. When you're depending on ammunition to do a specific job, that consistency matters.

Frequently Asked Questions
What exactly is a breaching round and how is it different from buckshot?
Breaching rounds use a specialized polymer shot payload designed to fragment or disperse upon impact, minimizing ricochet and reducing unpredictable projectile behavior. Traditional buckshot travels at lethal speeds well beyond its intended target. Breaching rounds like the SB12BR are engineered to deliver controlled performance at close range where precision matters most.
Will the SB12BR work in my standard 12 gauge shotgun?
Yes. The 2-3/4 inch shell length works in any standard 12 gauge shotgun designed for 2-3/4 inch shells. You don't need specialty equipment or modifications to fire these rounds. Always verify your shotgun is in proper working condition and follow the manufacturer's recommendations for your specific gun.
What does the polymer shot construction do?
The polymer material is designed to reduce ricochet and break apart after impact, minimizing secondary projectile hazards. This makes breaching operations more predictable and safer compared to traditional buckshot, which can ricochet or travel through doors unpredictably. It's a specialized design choice for a specific application.
Can I reload these brass cases?
Yes. Sellier & Bellot uses boxer-primed brass that's suitable for reloading. The cases can be reused over multiple loading cycles, making these rounds economical for regular practice or use. Follow standard reloading procedures and safety practices for 12 gauge shotgun ammunition.
