By lengthening the forcing cone in some Browning shotgun models, hunters and competitive shooters receive a performance advantage for more bagged game or a competitive edge at the range. Many shotgun enthusiasts pay high aftermarket prices for this modification, but it is considered the standard on many Browning shotguns. 

The forcing cone is the tapered transition between the chamber and bore that constricts the shot column. This long, gradual taper reduces stress on the shot column as it moves into the bore, reducing pellet deformation and resulting in more pellets in the center of the pattern. 

The longer forcing cone creates a gradual transition into the barrel. This engineered taper delivers three distinct performance advantages:

• Fewer Deformed Pellets: Gradual constriction reduces stress on the shot column, keeping the pellets perfectly round. 
• More Uniform Patterns: Round pellets fly straight. When pellets deform, they may stray away from your pattern, resulting in holes.  
• Denser Center Cores: By preserving integrity, more shots are packed into the center of your target.  

Competitors lack the longer, more gradual taper design feature on Browning shotguns. This geometry maximizes pattern uniformity and consistency without expensive aftermarket gunsmithing procedures. This system is a standard feature on:

• A5
• BT-99
• Citori 825 
• Citori
• Citori 725 (12, 20, and 28 gauge only)
• Cynergy

Browning pioneers Back-Bored Barrel Technology to complement the extended forcing cone. These two components work together to deliver the perfect balance of velocity, comfortable shooting, and a lethal pattern density.
