And how would I know? I still get blue patches. The marketing blurb says....
CFE 223 contains our Copper Fouling Eraser ingredient, originally used in military propellant, which greatly deters copper fouling and contributes to longer periods of top accuracy with less barrel cleaning time.
Other than loss of accuracy, what are the signs of copper fouling? How frequent / problematic is it? WHAT is it?
Your wisdom / experience appreciated.
