Deadlier by Design.
Real-world lethality is driven by physics - not just density.
We'll prove it.
If tight patterns and longer range is what you need, look no further. Powered by CuProX.
The shell that started the Boss movement, now loaded with CuProX Copper Shot.
Obsessively engineered to deliver Boss Factory Performance.
Why modern ballistic data challenges decades-old assumptions about copper, bismuth, and steel shot.
Tom Roster’s May/June 2026 Shooting Sportsman magazine column, “Copper Shot: What It Is and Isn’t,” takes a hard position on copper shot. That’s fine. But if copper is going to be judged, it should be judged by the same rules . . .
Boss Shotshells announced independent validation of its MkIII Shotshell Tester™, confirming 100% accuracy across 1,840 tests in identifying steel, tungsten, lead, bismuth, and copper shot. Conducted by UL Solutions for the U.S. Fish and Wildlife Service, the MkIII offers a fast, non-destructive method for verifying non-toxic shotshell materials in the field.
When bismuth supply dried up in 2025 we immediately went to work and scaled manufacturing of pure copper shot. Unsatisfied with the equal-to-bismuth performance, Brandon had an idea.
Precision-built steel for shooters who expect more every time they pull the trigger.
"I use Boss Shotshells every time. Not only do I kill more birds, but I’m making a better choice for the health of myself, the land, and the habitat I hunt. For me, it’s about preserving this heritage for future generations while using gear I can believe in, all because I choose a shell that’s American-made and supports our country’s veterans in everything they do."
"As an outfit owner, and someone who always hunts with one of their dogs, the immediate takeaway was the knockdown power. The lack of wounded/sailed birds is evident, and the knockdown power on our big late season geese in Canada is impressive! Great people, great company and a great product made in the USA, what more can you ask for?"
"The performance is obvious with every pull of the trigger. BOSS just hits different!! The heritage, ethics, and conservation of waterfowl have always been important to me and that shows in everything that BOSS does!!"
"Two things in the duck woods I love for them mallards to hear. A BOSS HEN and then some BOSS SHELLS. I’ve never had a shell that’s made such an impact that my buddies I was hunting with went and ordered some immediately. Then on top of a great product, the people behind the brand kick ass and are fun people!"
"You can add one boss shell to any cycle or shells and tell which one the boss is every time. They have a hotter load and longer range capability."
"The folks behind Boss aren’t just making shells; they’re making a commitment to hunters with ammunition that truly delivers. Boss shot hits harder and more reliably than any other shot I’ve used—it’s powerful, consistent, and built to perform. If you’re looking for ammunition that’s genuinely made by people who care, look no further than Boss."
