Total Barrel Dynamics
TOTAL BARREL DYNAMICS

Total Barrel Dynamics is the sum of individual features that make a Browning shotgun outlive and out pattern every other shotgun on the market. The first component is the barrel itself. We use the highest quality steel to ensure our barrels are impervious to the abuse of steel shot. Next comes the combination of back-boring and the addition of the Vector Pro lengthened forcing cone. This combination minimizes friction and stress on the shot column for less deformation and higher velocities. Lastly is the Invector-DS Choke System, tested and proven to provide tight patterns, consistent pattern percentages and the most even scaling and predictable patterns you’ll find. With an integrated system like Total Barrel Dynamics, you leave nothing to chance.

The strength of a Browning barrel is legendary, and is built to handle the punishment of steel shot. Unlike some manufacturers’ barrels whose guns face an uncertain future after shooting steel, we have long been at the forefront of dependable steel shot performance and durability.

Our barrels meet the strictest material and construction quality standards. The barrel blanks are made from rolled and tempered steel bars and are stress relieved to offer exceptional mechanical properties. The barrel blanks are then precision drilled, reamed and honed to exacting specifications. With proper care, a Browning A5 barrel will last a lifetime.

Steel shot After 500 rounds of steel shot, the higher-quality Browning barrel shows no wear.

Back Bored  BACK-BORED TECHNOLOGY

Browning was the first manufacturer to add back-boring to shotgun barrels to maximize pattern performance, shot pellet velocity and reduce felt recoil. Back-boring increases bore diameter specifications to decrease friction between the shot cup and the bore.

Reducing constriction from the forcing cone on the shot results in fewer deformed pellets for more uniform patterns, and keeps more pellets in the central part of the pattern where they're needed to bag more upland birds, waterfowl and clay targets. Our back-bore specifications represent the ideal bore dimensions. A larger bore diameter can let gases slip by the shot cup, resulting in both reduced pellet velocity and blown patterns. A smaller bore diameter means the forcing cone can deform pellets, leading to flyers and poor ballistic performance.

Steel shot The forcing cone of the competition’s barrel is pitted and damaged beyond repair after 500 rounds of steel shot.
