Rex, what are your thoughts on the newer IMR and Hodgdon powders with CFE (Copper Fouling Eraser) and how they impact copper equilibrium in a barrel? At first blush, this seems like a good way to keep your bore at a state of copper equilibrium that is at a lower level of overall copper buildup than without CFE. Potentially keeping you on the flat portion of the copper equilibrium curve for longer. Does it work out that way in the real world? When working up a new load for extreme long range, are the worth checking out?

CFE powders VS. Copper Equilibrium
CFE powders VS. Copper Equilibrium
Good question. I'm interested in the answer too.
I had the same thoughts and did some testing on a 308. Short answer, it just keeps less fouling in barrel, but you can still find equilibrium. That being said, I shy away from copper removing powders like CFE, Vihtavuori, etc in my extreme range rifle that I do keep at equilibrium. By using them you are introducing one more variable into the equation, one that is very difficult to measure and may change from lot to lot. I have other rifles where I use some powders with a copper removing agent, but they aren't my extreme range "first shot, one shot" rifles. Just my two cents.
Copper equilibrium has some suspect to clear over the version that was shared on this formation it was good to read. I can take some powers of the plants that have paperfellows this can be explained over some new formats that have some work police to get all on it.
