Product Summary

Patternmaster's Anaconda Mid-Range Choke Tube has Gas Over Constriction Technology within the patented Coil Zone. This Coil Zone is made up of channels used to harness gas expelled from the ammunition. The Coil Zone channels are spun in a negative twist to stabilize the wad for even, consistent patterns and keep the tube tight in the barrel. The Anaconda Mid-Range throws a modified pattern with distances out to 50 yards. This tube is safe and effective with steel or other non-toxic shot as well as lead shot.

Note: Testing done by Ballistics Performance has determined that ammunition with velocity of 1550fps and below will achieve the best results with Patternmaster Tubes. Not for use with slug ammunition.
