For shooters running 410 buckshot ammo in compact revolvers or single-shot home defense platforms, the Remington Ultimate Defense 3″ load brings five 000 lead pellets at 1125 fps — a practical balance of pattern density and terminal energy inside defensive distances. The .410 bore has historically been a sporting cartridge, but modern defensive loads like this one adapt the round for close-quarters scenarios where compactness, reduced recoil, and acceptable terminal performance intersect. Each 3″ hull is loaded with five .36-caliber lead spheres, roll-crimped for reliable feeding in revolver cylinders and smooth-bore barrels. Boxer-primed cases are reloadable for handloaders who prefer to dial in their own payloads.
Load Profile
The Ultimate Defense line from Remington reflects decades of engineering shotshell components — from hull geometry to wad design — for consistent ignition and controlled dispersion. The 000 buckshot pellet size (.36″ diameter) is the largest practical payload for the .410 bore’s narrow hull; five pellets represent a compromise between pellet count and individual pellet weight. At 1125 fps muzzle velocity, the load generates moderate recoil in compact platforms while maintaining sufficient downrange energy for defensive use within typical home-defense distances (7-15 yards). The non-buffered lead shot means pellets are not individually cushioned; pattern testing at your intended distance is recommended, as .410 buckshot patterns open more rapidly than 12-gauge equivalents.
