One other thing you might want to consider if you hunt in the cold is their cold weather performance. I don't know anything about their 28 gauge and .410 gauge shells but I put 6 of their 7/8 oz. 16 gauge loads through my Chrony in 20 degree weather and got a high of 1090 and a low of 1015 for an average of 1049.5. I even got lower results with RST 1 oz. loads. They gave a low of 923 and a high of 961.
If you've got a Chrony throw some in the freezer and freeze them down to about the temp. you expect to be hunting in and see what you get.
