Shotshell type ammunition includes a hull, a sabot disposed within the hull, and at least one projectile disposed within the sabot. The hull has a rimless first end that includes a primer for firing the ammunition. The hull also has a seat surface for seating the hull against a complementary seat surface in a firing chamber of a firearm. The seat surface is located a distance from an outer end surface of the hull at the rimless first end. The hull further includes an outer cylindrical side surface extending from the rimless first end of the hull to the seat surface of the hull. Methods of fabricating such ammunition includes forming such a hull, providing one or more projectiles within a sabot, and disposing the sabot with the one or more projectiles therein at least partially into the hull. Shotgun type firearms are configured for firing such ammunition.
