How can you tell if you got all the moly out of your bore? I shot 70 rounds of Hornady 55 gr. moly .223 ammo, out of a new barrel, and cleaned with Hoppe's bench rest after about 20 rounds at a time. Now I want to switch to non moly bullets. So I cleaned with Bench rest, then flitz, then PB blaster penatrating oil, then back to Bench rest, to get the moly out. With a bore light the barrel just gleams inside, but I still don't know for sure if it's all out. Again how do you tell, and will it hurt if it's not?
