Vector Pro™ Forcing Cones
Release Date: 1/1/2008
Back-boring is proven to improve shot patterns, and Browning’s new Vector Pro does it better than anyone else in the industry. Vector Pro features extended forcing cones that are over 2" longer than other systems. The taper is much more gradual than the 5° industry specification for even less shot deformation resulting in more uniform and consistent patterns. The Vector Pro geometry completely eliminates any step or double taper between the chamber and bore, a performance benefit no competitor or aftermarket modification can offer. Vector Pro’s long, gradual taper from the chamber down to the bore diameter is more expensive to produce, but the performance advantages are worth it.
