Okay, went back and reviewed some older info:
The Winchester Ball Powders have had de-coppering agent(s) listed on their MSDS sheets since at least 1997. Hodgy is listing CFE 223 on their September 2011 spherical powder MSDS, which is simply General Dynamics' July 2011 MSDS with a Hodgy cover sheet. That MSDS still has the same de-coppering agent(s) listed now as it did 15 years ago, so this 'new' powder is clearly a General Dynamics product with the time-tested de-coppering agent(s).
Interestingly, I do not see any de-coppering agents listed in Ramshot Powders' MSDS. I thought I recalled reading about them adding that recently, but apparently either I was mistaken or the item I read was.
