12 GA Warchief with CuProX Details

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 1475 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 delivered performance through density but carried 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 1475 fps delivers approximately 50% more retained pellet energy than steel at 1500 fps, and about 30% more than Boss Bismuth at 1350 fps.

• At 60 yards: CuProX with TurbuFlow at 1475 fps delivers approximately 74% more retained pellet energy than steel at 1500 fps, and about 35% more than Boss Bismuth at 1350 fps, reinforcing consistent lethality farther downrange.



Real-world testing supports the model. In gel testing, #3 steel at 40 yards produced approximately the same penetration as CuProX at 60 yards, highlighting how density combined with improved aerodynamic efficiency preserves usable energy farther downrange.


Not because density doesn’t matter.


Because efficiency multiplies it.

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.

I had put the warchief in as my 3rd round and the legacy copper in as my 1 & 2 shots. I had a few groups of ducks into the decoys and took 2 doubles with the loads. They hit hard and no cripples. What amazed me most was that the warchief on the 3rd shot had folded the birds on their way out that were close to 40yards out. I am definitely a believer in the copper and the warchief copper. Ill get me a case of the warchief for next season! I'm a believer and I have been for many years. Try it and test it. You’ll be impressed

3 early goose hunts in Michigan with them, absolutely crushes birds...even stretching shots beyond 60 yards.
Great alternative ( Verified Buyer )

I used to shoot Bismuth. Bismuth hits so hard and with it being almost nonexistent, I was looking for an alternative to steel. (I end up wounding a lot of birds with it.) One hunt under my belt with this new Warchief cuproX seems to knock the bird down way harder than steel ever thought!

I Took the Boss Ammo to North Dakota last week . the extra range of the warchief shined out on the flooded bean fields we hunted #5 is plenty for bigs ducks at 50 and anything under 40 is just dam Smoked !! Can’t wait to try the #4 I just received on these Mississippi Ducks and the #3 and 3/5 on these Tuff resident Honkers !!! I was skeptical like a lot of people about copper replacing the Boss Bismuth I had shot for years but being in the aerospace engineering department for years the math and the science made sense .to me so much that I had a case before they were deemed legal and now I have put them to the test where it counts in the field and marshes not only do you guys replace Bismuth you Bested it !!!

I loved the performance of the original bismuth Warchiefs a couple years ago and was eager to try out these new Warchiefs with CuProX. I must say I am impressed. They pattern fantastic out of my Benelli and no cripples. They pack a punch even with distance playing a factor. Steel just doesn’t compare to this. Highly reccomened!

I have spent the last two years shooting many different brands and materials of shells. After a recent trip to Saskatchewan I came to the conclusion that I will be exclusively buying Boss shells from now on! These new copper warchiefs crushed everything from passing ducks to a 50 yard shot on a 13 pound honker. I even got 2 partridge, 10/10 would recommend the 3/5s for everything
Great Product ( Verified Buyer )

Love the customer service. These people actually care about the consumer. Easy to get in touch with and reply quickly to questions or concerns. Oh, and by the way, the warchief is sick and deadly!
Amazing box ( Verified Buyer )

I loved the look of the box. This isn’t just for waterfowl! I am using it for squirrels , rabbit, pheasant and grouse.
