what is the forums thaughts on this stuff? i use a brand that turns purple when it starts to work. when i look at the barrel from the bore scope it is copper free after cleaning. i use that first and then run a brush through it. then i start using wet/dry patches until they come out clean. as everybody else i use a bore giude on every gun. i was just wondering if i was the only one who uses it. i also use a boresnake at the range to give it a range cleaning between rounds.
