I had some older remington express pheasant loads they were high brass 3 3/4 dram with a 1 1/4 oz #6 shot, I pulled them apart and visually speaking the powder was none other then Alliant blue dot I weighed the charges and compared them to some alliant shotshell load data I have this stuff could have very well been blue dot. I talked to a rep from remington at this years SHOT show and asked him if remington had ever used Blue dot powder in there pheasant loads, he stated that back in the late 80's it was very possible that they used Blue dot and various other alliant powders. I'm thinking ammo manufacturers use whatever they can get cheap.
