    12 Gauge Boss Copper Details

    Bismuth is out. Copper is in.

    The next generation of non-toxic shotshells is here. Boss Copper delivers the same trusted performance our Legacy Copper-Plated Bismuth shells were known for. Tight patterns, lethal penetration, and consistency you can count on - now engineered in copper.

    Here's the run down, straight from the shop floor:

    Boss Copper packs 94% the density of bismuth but brings 3× the hardness - meaning those pellets don’t deform as much. They cut through the air clean, with less drag and more consistency. The result? Uniform, punishing patterns that stay tight downrange and punch with identical penetration in ballistic gel.

    Copper’s softer than steel, so it’s old gun and fixed-choke friendly. Thirty-yard spreads are dialed-in tight with F-IM-Mod, and long shots sing with IM to Mod. Early field reports echo what we heard with bismuth - same knockdown power, same confidence - minus one thing: fragmentation.

    This is the next era of Boss performance.

    Mixed results - my fault ( Verified Buyer )
    ★★★★★ ★★★★★
    Eric (IL) | October 27th, 2025
    Bought the #5 and all our shots were at least 40 yards. Certainly knocks them down as I suspect the patterns are very good. I was using a light modified choke and hit just about everything I pointed at. However the one shot kills were disappointing compared to 3/5 bismuth. I can only assume this is my fault as I should have been using #4 or larger basded on range. I did swith to 3/5 warchief the last day of a 4 day hunt and the results were much better. I could have been using too small of shot or too open a choke. We did harvest a lot of ducks, but I wouldn't buy #5s for the same situation again. For reference we were shooting a mix of mallard and woodies.
