    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.

    Got some Copper 3/5’s, & 5’s last week & used it in the Goose field this last weekend. Very impressed with the performance of the Copper. Absolutely Crushing birds! Well played Boss folks!! You’ve successfully overcome the other non- toxic issues.

    Boss shells are extremely effective. I've been very pleased with their products, fast delivery and customer service. I recently had a minor issue with an order and Boss went above and beyond to remedy it. Allyson was extremely helpful!

    Tested these 3/5 3” shells out of a SX4 code black and GForce Muller passing choke both 12ga. Both patterned good out to 40 yards. Hope this helps someone choose the right choke for their gun. Good luck all

    Purchased both 3” & 3.5” My STOEGER 3500 likes the 3” the most. At 30 yds 3” & 3.5” were very even when it comes to pellets on paper But At 50 yds the 3” were considerably more effective. I’ve made my choice for our MO duck hunt In January.

    Been using 3" #4's for divers and big water ducks. The new Copper is lethal out to 50 yards and eliminates chasing wounded birds in high chop. Limits of Cans and Blue Bill's that last couple weeks. Working great
    Just fantastic ( Verified Buyer )

    Got these for a duck hunt so my son could use his Remington 11. It was a slow day in the blind but the wood fool and blue bill he shot were stone dead. Can’t wait to test them on geese.
    Less shots more results! ( Verified Buyer )

    Chase | November 20th, 2025
    The boss copper is a lethal round I purchased the 2 3/4 3/5 shot and had no problem dropping birds at what would normally be a questionable distance. In addition with this lethal load I used less shells because the first shot was doing the trick. I will be buying more. This was shot through a browning maxxus.
