.410 bore is the smallest common shotshell chambering, firing a light shot charge with very light recoil, used for small game, pest control, and clay/skeet shooting.

The .410 (technically a bore size, not a gauge) fires a small shot payload, producing very light recoil but also a smaller, less forgiving pattern that generally demands more precision than larger gauges. It is used for small-game and pest shooting, skeet, and informal target use, and certain .410 loads are also marketed for self-defense in .410-capable firearms. Ammunition is available but typically costs more per shell than 12 or 20 gauge. It suits shooters who prioritize low recoil and accept a smaller payload, though it is often considered more challenging for new wing-shooters than a 20 gauge.
