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?
