re: leading. I was convinced that I was getting my rifled .50 bore sparkling clean, judged by a drop light, with warm water, a touch of soap, and scrubbing with patches. I even used a brush on the breech plug face.
Then I got a bore scope working... At first I thought the crud was the protective grease I coat the bore with after cleaning. I scrubbed that outs, until the scope showed the bore was really clean. That left white splotches on the lands and grooves, which I assume is lead oxide- which I can't scrub off, even using a .45 bronze brush, wrapped with 0000 steel wool. Anywhere else, the pattern would look just like a mold bloom.
I used lubed PRB, so I don't understand how the deposit is getting there - or how to remove it. What works? Thanks.
