The late season CO honkers didn't stand a chance out to 45 with these. Great product and is just flat out lethal.

I used these for 2022/2023 duck season. Drops them dead in their tracks. Ordered another case to load up before the next season rush rolls around! I would definitely recommend.

Great product

These hit hard. Yes they’re rather expensive but they’re worth it. They are much better than any steel you can buy and much cheaper than tungsten. You will not be disappointed. If you do your job… so will they.

Had a killer shot on a teal about 40 yards are so, improved cylinder choke. Very happy to see that duck drop like a brick. Will be using the #7s for gambels and mearns quail. Thanks boss

Hey guys this is my fourth year of shooting boss 3” 20 gage 3/5’s out of my M2 Benelli . I shoot a lot of big geese up here in the Yellowstone Valley and Long the Big Horn river. All the guys I hunt with shoot 3” #2’s or 3.5” #2 or BB’s steel and I kill ‘em with my little 20 gage and they have a hard time believing what their own eyes are seeing when those big ass suckers fold up like a lawn chair. Thanks for making such a wonderful product keep up the good work Thanks

Great BANG for your buck

These things are way better than shooting steel. Hits harder and helps you drop more ducks. I used them one day in my 20 gauge after a friend recommended them and I will always shoot Boss in my duck gun

Crane Crusher
Steve Spragg (Granbury, TX) | December 12th, 2022
I have recently transitioned to a 20 gauge gun for waterfowl hunting using steel shot for ducks. I decided to buy some Boss #3/5s for a recent Sandhill Crane hunt. The first crane of the day tried to skirt the spread at 50 yards. The guide called the shot so i jumped up to give it a try. I was pleasantly surprised to see the bird fold up and fall to the ground - obviously dead - earning a “nice shot” from the guide. I was so impressed with Boss performance that I sold all of the rest of my steel shot and have now converted entirely to Boss shells for all of my waterfowl hunting.
