    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.

    I exclusivly shoot BOSS now after going full on WarChief when that came out. I was sad to see the Bismuth supply issues. However I just took a case of the Copper 3's to Canada 3 weeks ago. And I will say the Copper is just as impressive as the Bismuth. Crushes Cranes, Geese and Ducks. I am convencing my hunting partners daily that the results from BOSS is worth the cost and cost effective as your crippled bird numbers are drastically night and day different compared to the everyday steel out there on the market. Bravo on another great product and I am proud to support MADE IN THE USA and Veteran owned company. I will not shoot anything but BOSS at birds ever again!!!

    These Copper pellets outperform bismuth in my opinion. I have gone through about 40-50 of these shells, and the ducks I've actually hit have been Stone. Dead. Every. Time! 10/10 Worth the wait, price is still tough to stomach, but better than going through twice as much steel. Will be making another purchase.

    The new copper 3/5 are very similar to the original bismuth that Boss started out with. We shot redheads on big water, Canada geese, and big mallards. All we stoned dead and saw excellent penetration through body and exit wounds at 30-40 yards. I have been hunting for 39 years and this copper out performs everything since I was able to use lead!

    I bought a couple boxes, to compare their performance to the original 3/5's. It's early season, my shooting is still off a tad, and I'm breaking in a new semi-auto. With that said, I'm not disappointed. My first shot (modified choke) dropped 2 gadwall at about 25-30 yds. They were just lifting off the water. Both were stone dead. I was making some of my best shots, this season. Now some can be attributed to getting my act together, but the loads were doing their job as well. All in all...they are a winner.
    Hope copper works ( Verified Buyer )

    We go to Devils Lake ND every year. We have about 2 cases of War Chief and Legacy 3/5 and a case of 2"s in bismuth. I ordered a box of copper 3/5 and plan to try those first on 10/17.

    Decided to make the jump from steel this season and dang it, this copper shot hits hard! Price really evens out too when you don't have to burn shells water swatting cripples!
    Patterns well! ( Verified Buyer )

    Got a box of the 3" 3/5's to pattern my new auto loader, along with a few other brands to see for myself what was the best option. The BOSS shotshells delivered. They patterned just as well as one of the bismuth loads and much better that the other steel loads that I tried. I will be buying more!

    Took this stuff out opening weekend and it worked perfectly. Loved the old bismuth but this seems to be a great replacement. Will be buying more.
