Patternmaster Black Cloud FULL Choke is a constriction choke that is compatible with the Black Cloud Ammunition or any ammunition with a "Flight Control" wad. It has also proven to shoot well with other brands of shotgun ammunition as well. Patternmaster worked closely with Federal Premium® Ammunition company to design a tube that enhances their “flite control” wad inside Black Cloud and Prairie Storm ammunition. The design of Patternmaster’s Black Cloud tubes enables the use a Full constriction choke with steel shot because the tightest portion of constriction is located outside the barrel.  Expect full patterns with an effective range from 30 to 60 yards.
Note: Testing done by Ballistics Performance has determined that ammunition with velocity of 1550fps and below will achieve the best results with Patternmaster Tubes. Ammunition containing flight control wads may not perform using a shotgun with a ported barrel.
Not for use with slug ammunition.
