For the function of the round. The 5.7 rounds does not operate like a comon rounds like 45,9mm etc. The brass needs a coating to properly cycle at the pressures the 5.7 operates at, extract etc.

the coating helps the round "stick" in the chamber slightly longer to allow the blowback action to do it's job safely

So how do you guys clean your rounds so you’re not removing the coating?
