CuProX Shot has 94% the density of Bismuth yet is 50% harder and infinitely more malleable which yields a tougher pellet. This toughness, when married to our Boss Warchief line of bio-engineered wads yields ballistic performance that exceeds the capabilities of our legendary Copper-Plated Bismuth.

CuProX Shot maintains its spherical shape during setback and choking. As a result, more total energy is transferred when compared to Copper-Plated Bismuth moving at the same muzzle velocity. When measured in ballistic gel, the dispersion of the deepest (most energy) to shallowest (least energy) is 300% tighter than Copper-Plated Bismuth.

Insanely dense long range patterns result from using Full Chokes. 94% inside 30” at 40 yards has been achieved shooting a factory full choke with a Benelli M1/LFC. CuProX Shot is 50% softer than Steel, making it a safe alternative and drop-in replacement for both lead and bismuth.

CuProX Shot is 100% USA Sourced and proudly manufactured in Bridgman, MI. Tariffs, trade wars and global metal shortages will no longer affect Boss’ ability to product the world’s highest quality shotshells.
CuProX Shot is 99.9%+ Corrosion Inhibited Copper. Corrosion Inhibited Copper Shot has been deemed Non-Toxic by the USFWS.

CuProX Shot will be officially added to the USFWS shot approval chart once the Boss Mk III Shot Tester is approved and is published in the Federal Register. Anticipated date is 12/25.
