I have a 6BRX in an 8 twist 3groove barrel, I generally clean after 25 rounds at the range and shoot 50 shots per outing. I have never gotten good accuracy from it even though I use more powder than any one here on the forum and still get no (NO) pressure sign. At home I went at the bore with KG12 for 3 days and the bore,through the scope appeared a gold or yellow color. I was afraid that it was from the KG12 (the highest rated copper solvent)because it has a yellow color itself. I then tried Montana Extremes Copper Killer with negligable results (on the color) I just wonder if anyone else has the same experience?
