Perfect brass disease

My reloadable brass doesn't have to shine, just be clean of debris. My black powder 45-70 brass is really nasty looking but still functional. Never have found a way to clean black powder brass back to shiny.

For a precision rifle that might be worth it but for a caliber like .45 colt i dont see any advantage except esthetic .

I have a dedicated plastic bag filled with 75 .45 Colt rounds that i have reloaded at least 35 times.......i don't trim the cases, i don't always tumble them in walnut shells and at the range i get the same accuracy results vs. the same load in brand new brass.

Resizing dirty cases with carbide dies takes a lot less force than cleaned, tumbled cases do.

The story of brasso making brass brittle is all over the internet. It's another internet tale or wives tale.

Brasso does remove a trace amount of the corroded brass in order to make the brass shine. But it does not penetrate the surface of the brass and alter the alloy of copper and zinc.

The story was probably started by someone picking up badly corroded brass at a shooting range and polishing them until they shined. And the walls of the polished brass was so thin that the case ripped apart on firing.
