The universal gauge gets the deepest shotshell inventory in the shop: clay target loads by the flat, field birdshot, waterfowl steel, turkey magnums, rifled slugs for deer zones and defensive 00 buckshot from Federal, Winchester, Remington and Fiocchi.
Defensive users - pattern your buckshot at home-distance ranges before trusting it; loads print differently gun to gun. Clay shooters, ask about case pricing before league season.
