EVERYONE Do Please note, I ABSOLUTELY DID ""NOT"" recommend anyone load shells from the 1950 Lyman data. In fact if you go back & read my post I ""Cautioned"" those loads were put up in paper shells, with card & filler wadding, not present day components.
As to the 2 3/4 drams of Green Dot this was someone elses post, but it does seem that today as it was in early smokeless days, people do not fully understand the difference between Drams & Drams Equivelent. The DE is a given amount of a smokeless powder to give similar balistics to that many drams of Black Powder & has no reference to its actual weight or volume.
I have not looked up any current data on this, but in the not very distant past & with most components still available Alliant did list a few Green Dot loads for 1Ľ oz of shot at what would have been about a 2 3/4 "Dram Equivelent". These were low velocity loads giving around 1100 FPS at normal pressures. The American Rifleman ran an article on low velocitie loads some years back primarily for a 1˝oz load with Unique powder at around this same 1100 FPS velocity. It was developed & pressure tested by then Hercules powder Co & done for both card & filler or Remington Power Piston wadding. This was while lead shot was still legal for waterfowl & I successfully used a good many of these loads. They were basically classified as a 3"DE"-˝oz load, charge as I recall was 23grains Unique (But don't load this unless you can find Data). To my knowledge even though these were worked up & certified by Hercules they never placed them in their Handloaders Guides.
The question I was answering of course was "What did they shoot Back Then". Obviously if you load up in compression formed cases with special long range plastic shot cups you are not going to be duplicating what folks such as Nash Buckingham etc shot. I could go even further back & list loads from a 1913 LAC catalog & they would literally scare the socks off you with todays components.
Incidently in his writngs Nash stated that using the 1 3/8oz #4 Lubaloy 3" SX load from Bo Whoop #1 he could consistently kill Ducks or Geese to 60yds. He further stated he could "Scratch" them down to 70 yds, but only if he were hungry & accompanied by a very good retreiver.
