When using ER to clean the barrel, is it necessary to lube afterwards or is ER self-lubing like CLP(which is what I use as lube anyway)?
Also, I understand that it cuts lead but not copper. I use FMJ pretty much exclusively. Should I use a copper cutter every say 500 rounds or so? Or is that too often?
