Aguila Minishell shotshells are only 1-3/4" long, and greatly increase the capacity of pump-action shotguns. They work great in Winchester 1300 shotguns, though other pump guns may not cycle reliably without modification. Perfect for use as low-recoil ammunition for single-shot or double guns as well. The buckshot load features a combination of #4B and #1B shot, the slug weighs 7/8 ounce, and the birdshot is 5/8 ounce. 20 rounds per box.
