410 BORE Boss Shotshells

These legendary Copper-Plated Bismuth shells are running low - and once they’re gone, they’re gone. 

When Bismuth supplies dried up earlier this year, we set out to build the next generation in waterfowl ammunition - one worthy of carrying the Boss name.

So we did what we do best: got to work. After months of development, relentless testing and refinement, Boss Copper is in-stock.

Boss Copper was engineered from the ground up to hit just as hard, pattern just as tight, and be a drop-in replacement for our OG Copper Plated-Bismuth that became trusted across the industry as the benchmark for performance. 

At 94% the density of bismuth, consistently yielding patterns in the mid-70's at 40 yards with identical penetration to bismuth in ballisics gel, Copper holds it's own as the new Boss standard.
