Winchester AA Features The Winchester AA .410 load uses proven hard shot to maintain pattern density and consistency an important factor in a small-bore gauge where pellet count is already limited. The AA wad design distributes the #9 shot uniformly as it exits the barrel helping shooters maintain tight even patterns at typical skeet and sporting clays distances. Winchester s high-strength hull is built to withstand repeated firing and reloading cycles without deforming or splitting. This combination of proven components makes the AA line a mainstay among small-bore competitive shooters. Winchester pairs its best-in-class primer and clean-burning powder for reliable ignition and consistent velocity across the entire case. Each box holds 25 rounds and the case totals 250 giving shooters a dependable supply for a full season of trap skeet or sporting clays competition. The 2.5 hull length is standard for .410 target loads ensuring smooth cycling in break-action and pump .410 shotguns alike. For shooters who compete regularly in small-bore disciplines this case lot delivers the consistency Winchester s AA line is known for.
