After shooting cast bullets out of my Garand for some time, I always scrubbed it out with chore boy, and it appeared clean from the muzzle. Recently, I bought a bore cam, and it showed that I was missing spots of leading in the bore, that scrubbing could not touch. I found that Lewis Lead remover system carries a 30/32 caliber head as well as the usual 38/357, 44 cal and 45 cal. After screwing it on a cleaning rod, and pulling it through the bore twice, it proved to be effective. Just trying to pass on some cleaning knowledge to you guys that don’t have a bore cam. Good shooting!
