    Shot the 20ga two of three hunts last week. One hunt over water the other a feed field. Shot snows and ducks and the 20ga copper 3/5 & 4 shot does a pretty Damn Great job at folding them up. Most shots were 30-40. Since shooting Boss the last handful of years I have become a lot bigger fan of shooting my 20 & 28 gauge guns on hunts I never use to consider it. Quality ammo makes a huge difference in that!

    Took a couple boxes on a Kansas pheasant hunt to try them out before duck season in Arkansas. These shells rock! After a few of the shots that were made with 20ga, everyone wanted to know where to get some. I've been using legacy bismuth for several years now and could not tell much difference.

    Have shot these and the 16 gauge copper. Love the product and it’s 20 bucks a box less than other brands inferior bismuth.

    I have been using this ammo since I started using my 20 gauge last year and have had nothing but great results. This is like turning back the time to lead. Great range, hit hard and kill the targets. Very good pattern. No hangups. I am using a 20 gauge M2 Benelli. No more 12 gauge for me. Pricy but well worth it.

    Boss shells just flat out work! Can't wait for the smaller shot sizes to come out for upland hunting.

    I had to back off the mag for teal season, just too harsh. Great for big ducks including geese. i will say Im using a Super Black Eagle 3 with a Briley custom job and choke. I have had more jams this year than any other I remember. I clean and lube after each weekend, running about 25-30 shells through it. Very please with ammo though, longer more accurat shots with fewer cripples.

    I have been closely following the “evolution” of Boss waterfowl shells, given the recent massive shift from Bismuth. I did a lot of research during the off season and was prepared to buy some Warchief shells when the Bismuth change prevented that. I have just bought a case of the new copper 20 ga shells (3/5), and look forward to trying them vs the top Tungsten and Bismuth alternatives I purchased before Boss released their new copper shot. Can’t wait to see Boss release a copper Warchief option. From what I’ve seen, that will come out around mid year next year.
    New boss not near as good ( Verified Buyer )

    I'm a repeat customer and was shocked by the new shell's inability to kill a duck. Felt like steel shot with as many follow up shots that had to be made. Last year I used the old bismuth mix 3/5s and 4s and hardly had a cripple or follow up shot. This year I used the new copper and was a night and day difference. Many ducks to follow up shots on, couple to chase down, some ducks with 3-4 water finishing shots to stop them. Definitely not worth the price difference of steel.
    well pleased so far ( Verified Buyer )

    Season is not open so I have not been hunting yet. I have patterned my a300 20 ga with the #3/#5 shot using the improved cylinder, modified, full, Carlson Cremator mid range and long range chokes. Great, even patterns with all of them but the full and long range are too tight for where I hunt most of the time. I haven't done it yet, but I will be doing the same pattern test using the #5 shot before I decide what I will buy a case of. I'm looking forward to another season hunting with the BOSS.
