Pre-Order | 20 GA Warchief with CuProX

Warchief was built around one standard:

Uncompromised downrange performance.

Built around CuProX™ with TurbuFlow™, Warchief applies aerodynamic engineering to preserve pellet energy and maintain pattern integrity as range increases — extending lethal performance without sacrificing consistency.

Running CuProX™ with TurbuFlow™ at 1500 fps places the pellet within an optimized high-performance window — balancing pellet energy, pattern density, and aerodynamic efficiency to deliver reliable terminal performance at distance.

For the same shot size:

• Steel often relies on higher muzzle velocity — such as 1500 fps — but sheds energy quickly due to lower density and higher drag.

• Boss Bismuth Alloy Shot delivers performance through density but carries greater aerodynamic resistance.

• CuProX™ with TurbuFlow™ improves aerodynamic efficiency, allowing more usable pellet energy to be retained as distance increases.

At typical Warchief distances:

• At 40 yards — CuProX™ with TurbuFlow™ at 1500 fps delivers approximately 50% more retained pellet energy than steel at 1500 fps, and about 30% more than Boss Bismuth Alloy Shot at 1350 fps.

• At 60 yards — CuProX™ with TurbuFlow™ at 1500 fps delivers approximately 74% more retained pellet energy than steel at 1500 fps, and about 35% more than Boss Bismuth Alloy Shot at 1350 fps, reinforcing consistent lethality farther downrange.

Pattern Control Where It Matters

Warchief with CuProX™ with TurbuFlow™ is engineered to maintain dense, uniform patterns at extended distances while preserving flexibility across choke configurations.

Choke it as tight or as open as conditions demand.

• With full chokes, shooters can expect tight, efficient patterns designed to remain uniform as distance increases.

• For tighter shots, opening the choke produces larger, dense, uniform patterns driven by aerodynamic stability rather than excessive velocity alone.

In testing, Warchief produced approximately 60% pattern density at 60 yards. With the right pellet size and a capable shooter, the shell itself no longer becomes the limiting factor — placing responsibility back where it belongs: on judgment and execution.

CuProX™ with TurbuFlow™ maintains pellet integrity on impact, eliminating the fragmentation sometimes associated with bismuth while delivering consistent penetration.

Deadlier by Design.
