I gave up on the swaging idea. Lee has done away with their original swaging die kits and now use actual lee dies with an adapter, too pricey of an experiment for me. My RCBS cowboy dies arrived. Now understand that I'm lazy and like that a single powder measure setting works for multiple loads for multiple guns. CAS is not an accuracy game so minute of sass target is ok for me. I use 5.2 gr of Clay dot for my .45 lc (200 gr pistol) and (250 gr rifle) and in my .44-40 (210 gr musket). Naturally I tried it in the .38-40 (180 gr New Service) but found it snappy, not accurate and hard on my arthritic knuckles. So I swapped my Dillon measures and tried my .45 acp/ autorim load of 4.5 gr of red dot. Good load, doesn't hurt, accurate too. As to my secondary question, I agree that it was a Winchester marketing ploy. Have you ever noticed that there are so many different sized boxes of kellogs corn flakes on the cereal aisle? It's all about taking up space on the shelves.
