    Hunted specks in Arkansas this weekend with a couple big groups. I had my 20ga Citori - all I know is there were multiple times the birds I was looking at when I shot crumpled when I pulled the trigger. I'm not claiming them, I'm not jumping up and down like I'm a stone cold killer. But, I can say, on multiple occasions, the birds I was looking at folded. On one occasion, the speck I was looking at and even the one next to it folded like a rag doll.

    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.

    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.
    Bad to the BONE

    Such a smooth shooting, and deadly product. Really hard to take my money else where when this stuff is made 1-1/2 down the road.
