Well I went through the scouts barrel again trying to make sure I didn't have any copper up by the muzzle, butch's bore shine and bronze or brass brush and then more cleanup with patches I think it's clean. I have been searching for a reason my groups opened up some recently and I did notice that it appeared my flash hole through the tungsten bushing may have had some carbon buildup so I worked on it with the cutting torch cleaning wires and it appears to now be a touch bigger. also yesterday I stopped in cabelas and bought a set of the warne fixed steel verticle scope rings. I just feel the double screw setup on the bottom of the rings is more sturdy in connection to the base. I have another medical treatment tommorrow and then I'll be ready to give it a go again. How often do ya'll have to clean the flash hole in your breech plugs when using large magnum rifle primers with hankin's His system? just curious. I'm social distancing out here on my farm, and talking to my dogs and cows like they are people, lol kip
