For shooters running a 410 bore platform in a home defense role, the Winchester Super X 3″ buckshot delivers five #000 lead pellets at 1135 feet per second. This 410 bore buckshot load balances penetration and pattern density in a compact shotshell — each pellet measures .36 inches in diameter, and the five-pellet payload keeps recoil manageable for smaller-framed shooters or those new to defensive shotgun work. Winchester uses a lead shot payload without buffering, boxer-primed brass cases, and smooth-bore barrel compatibility across 3″ chambered 410s.
Built for the Box
Winchester manufactures this load in the United States, using non-corrosive boxer primers and reloadable brass hulls. The five-pellet count keeps pattern spread tight at typical home defense distances — under 15 yards — while the 1135 fps muzzle velocity delivers enough energy per pellet for barrier penetration through interior walls and soft body armor is not a consideration. The lack of buffering means you may see slightly wider patterns than buffered loads, but the tradeoff is lower cost per round and consistent ignition across temperature ranges.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Observe the four rules of firearms safety at all times — treat every gun as loaded, never point at anything you are not willing to destroy, keep your finger off the trigger until ready to fire, and be certain of your target and what lies beyond it.
- This product contains lead, a chemical known to the State of California to cause cancer and reproductive harm — wash hands after handling and follow all applicable Prop 65 guidelines.
- Store buckshot ammunition separately from target loads to avoid confusion — buckshot overpenetrates interior walls and creates greater risk to bystanders in dense housing.
