发明名称 WATER RESISTANT SHOT WAD
摘要 A water resistant shotshell (10) has an internal moisture seal (32, 86) to preclude moisture intrusion into the propellant charge (26). The seal is at least one flexible tapered lip (32, 86) on the plastic shot wad (12) which is compressed against the inside surface of the shotshell tube over the powder charge. The preferred embodi-ment is a two piece shot wad having a shot cup portion (22) and a wad portion (24). The wad portion (24) has a central disk portion (28) and a tubular rim (30) terminat-ing in a pair of opposing flexible lips (32) which provide a dual moisture seal.
