Abstract
A water resistant shotshell has an internal moisture seal to preclude moisture intrusion into the propellant charge. The seal is at least one flexible tapered lip on the plastic shot wad which is compressed against the inside surface of the shotshell tube over the powder charge. The preferred embodiment is a two piece shot wad having a shot cup portion and a wad portion. The wad portion has a central disk portion and a tubular rim terminating in a pair of opposing flexible lips which provide a dual moisture seal.
