Pattern Master Choke Tubes
Description
How conventional chokes work
Until the introduction of the Patternmaster™ choke tube in 1993 all chokes used constriction or funneling as a way of controlling patterns. This works relatively well except for two problems:
As the wad carries the lead shot down the barrel to the choke the shot is squeezed and the shot string becomes very long. Tests have proven that shot strings from conventional choke tubes can be up to sixteen feet long. This is the same principle as pouring sand through a funnel. All of the sand can not exit the funnel at the same time. With a shot string sixteen feet long the amount of pellets that actually hit the intended target is very few.
The shot cup or “wad” used in shotgun shells has always been a problem for pattern control. Shotgun shells use a wad to carry or push the shot down and out of the barrel. These wads are made from paper or plastic. When exiting the barrel the wad, being much lighter than the shot it carries, pushes through the shot string before falling away. This interaction destroys shot patterns.
