Gentlman I have another question for you, when you clean your rifle barrel do you remove all the copper fouling or do you leave some inside the barrel? After I get done shooting it takes me about 35 to 40 patchs to remove all the copper from the rifleing and this is a major pain in the ass! Is there any accuracy to be gained from leaving a little bit? I tend to clean my barrel until there is no copper fouling at all but you must understand that when I go shooting I usually put at least 40 to 60 rounds through the gun and I do tend to run a least a couple of patchs soaked with solvent, is my cleaning overkill?
