The steel shot in the ZZ Canard shell flies at 440m/s, making it the fastest in the WINCHESTER® range of steel shotshells. The high velocity is mitigated by the relatively low load weight to maintain a comfortable shooting experience. The shot protector wad holds steel shot that is covered in a fine coating of tin to protect against corrosion. It is a high-performance shell for steelshot proofed shotguns. Special steel-shot protector wad.
