This ammo improved my hit to kill ratio and could not be happier with my purchase. Will be ordering more in the future.

I’m sold on Boss for duck and goose hunting!! It stacks up limits of ducks and geese!
My next season shell
Panchothings (San Diego) | February 24th, 2023
After a back and forward with different steel shells and split steel and bismuth. I jumped into trying a more dense pellet. This shell patterned amazingly with my choke tube and my benelli sbe3. I’ll be ordering couple of cases in 3” and couple of cases in 2 3/4. I’ll be rocking these guys for now on, no more cripples baby. I’ll be shooting these exclusively next season and I’ll write a second review after season is over.

I've just become a shot shell snob
Tom T (OK) | February 2nd, 2023
I bought a bulk box of 3" 3/5 1 1/2 oz. I used these loads pretty exclusively this season. I will be using them EXCLUSIVELY from now on. Big duck, small ducks, doesn't matter. These shells just kill ducks. cripples were non existent. You hit the duck it hits the water. Awesome product.

Soft Shooting, Hard Hitting
Aaron H. (Lubbock, TX) | February 2nd, 2023
I bought these last summer but wanted to see how they actually shot over a season before I left a review. Having shot primarily 3.5in steel #2s prior to this season, I was very pleased with the way the Boss shells performed. Much softer shooting than a typical 12 gauge magnum load, but still have excellent penetration and knock down, even on late-season birds carrying some extra padding. I ran close to 200 rounds through my gun (Winchester SX4) over the course of the season and had no issues with cycling or hangs. I'm very pleased with Boss shells after shooting with them for a season and I would definitely buy again and recommend them to others.
Best money can buy!

I've hunted waterfowl for over 20 years and there is nothing that comes close to Boss shotshells. I've shot steel, bismuth, tungsten, hevi-shot, hevi-metal, you name it. I'm too old to be chasing cripples and I don't have to anymore. Quit spending your money on Sitka clothes and motion decoys b/c if you can't kill them what's the point?!

Duck Loads
Alan (Easton Md.) | January 31st, 2023
Great Duck load with less felt recoil than steel. This arrived at my door in 3-4 days. Thanks Boss
