MD,
Maybe you could find out from Hodgdon if they are using Tin Dioxide or Bismuth in CFE as the decoppering agent.
I remember reading a statement by Julian Hatcher that they had tried loading shredded tin foil on top of the powder in the old 30.06 at Aberdeen Proving Grounds for copper fouling problems.
After this test DuPont actually came up with a tin (Dioxide) additive to their powders(IMR to be exact) for this specific purpose.
Just wondering if they had a new formula for this or if they just decided to upgrade a 100 year old Idea for marketing purposes only.
